Solving a Mystery in Philadelphia Voting Patterns

A long time ago, I posted a series of posts analyzing the swing state Pennsylvania. One section of this series focused specifically on the city of Philadelphia. This section analyzed Philadelphia’s vote by precinct results and mapped out the results of several previous elections.

Of particular interest was the difference between the results of the 2008 presidential election and the 2008 Democratic primary, which illustrated a political divide not seen in presidential elections: between Democratic-leaning white Catholics in the northeast and Democratic-voting blacks in the west.

Here is Philadelphia in the 2008 Democratic primary. Take a note at the region the question mark points to, which this post will discuss:

Here is Philadelphia in the 2008 presidential election:

Most of the different voting patterns between these two elections is fairly easy to explain: blacks in west Philadelphia voted for  Barack Obama both times, while white Catholics in the northeast voted strongly for Hillary Clinton in the primary and then lukewarmly Barack Obama in the general election. There is generally a scaling relationship between the two groups: as an area gets more white and less black, its support for Mr. Obama decreases in both elections.

There was, however, a group of precincts in Philadelphia which did not follow this model. These precincts are marked by the question mark in both maps. This group behaved quite strangely. It gave incredibly strong support to Ms. Clinton in the primary and then even stronger support to Mr. Obama in the general election. In the map of the 2008 primary, a number of these precincts cast more than 70% of their ballot to Ms. Clinton. All of them then vote more than 90% Democratic in the general election.

This behavior was quite puzzling, and something that the model did not explain. Initially this author hypothesized that these voters were white liberals in gentrifying areas of Philadelphia and then eventually forgot about the mystery.

The answer, as it turns out, was not white liberals. Here it is:

The mysterious precincts were Hispanic!

The above image was created using Daves Redistricting Application. Due to the tremendous efforts of David  Bradlee, one can map the ethnic composition of every state in incredibly detail.

This provides some interesting insight into the behavior of Hispanics in inner-cities. If what holds for Philadelphia also holds for other cities (which is not a 100% certainty), inner-city Hispanics strongly supported both Hillary Clinton and then Barack Obama.

It is an insight provided by Daves Application which can be extended to many other areas and groups.

Analyzing Swing States: Pennsylvania, Part 3

This is the third part of a series of posts analyzing the swing state Pennsylvania. Part four can be found here.



Philadelphia’s Suburbs

There used to be a time when Republicans could count on Philadelphia’s suburbs to counter Democratic margins from the city. This is Philadelphia, circa 1988:

Not anymore. Philadelphia, 2008:

Photobucket

(Note: Because the Times stopped updating before all absentee/provisional ballots were counted, this map does not fully reflect the actual results. I have corrected the discrepancy.)

Indeed, in 2008 President Barack Obama’s suburban margins were so great that Democrats did not even need Philadelphia to win Pennsylvania.

Philadelphia’s suburbs stretch across four counties: Bucks, Chester, Delaware, and Montgomery. Bucks contains more working-class, Catholic communities. Chester, on the other hand, is more exurban and conservative (in this century, Democrats have only incontrovertibly won the county twice – in 1964 and 2008).

More below.

The suburbs hold more importance than implied by the above maps, which tend to exaggerate Philadelphia’s size due to its one-sided voting pattern. While the city’s population continues its long, slow decline, its suburbs have grown at a rapid clip. Today, the number of votes they hold almost doubles the city’s reservoir.

Photobucket

While regional differences exist, Philly’s suburbs do have one thing in common: they compose the wealthiest area in the entire state. Chester, Bucks, and Montgomery Counties rank #1, #2, and #3 in the state’s median household income. They also lack diversity; the census classifies around 90% of Bucks County residents as non-Hispanic whites.

Given these characteristics, one might expect Philly’s suburbs to be rock-hard Republican strongholds. Until recently they did vote strongly Republican; Democrats only won the suburbs twice (in 1964 and – due to TR’s Bull Moose candidacy – 1912) before 1992. It was President Bill Clinton who changed this pattern; in 1992 he barely managed to turn Bucks, Delaware, and Montegomery blue (his greatest margin was 3.4%). Ever since then Democrats have been doing better and better.

Photobucket

This shift does not constitute an anomaly; Democratic candidates since Mr. Clinton have been winning a number of wealthy, white suburban counties that used to go strongly Republican. Before Clinton, Long Island and Westchester consistently gave Republicans double-digit margins; today they’ve voted Democratic for the past four consecutive elections. Detroit’s suburbs – Oakland and Macomb counties – have gone from Reagan Democrat fortresses to regions John Kerry tied. Senator John McCain barely won Orange County, that symbol of suburban Republican might.

Montgomery and Delaware counties are especially Democratic-friendly. They  identify more with the populous, sophisticated northeastern seaboard than the more conservative Midwest. As such, these counties by nature sympathize with liberal sentiment; George W. Bush lost both by double-digits. This does not necessary mean, however, that Montgomery and Delaware constitute bastions of acceptance; products of white flight from Philadelphia, they can at times be fairly hostile to people who are considered different.

Increasing Democratic strength in these well-off suburbs portends great trouble for Republicans. In 2008, Mr. Obama’s performance in Montgomery and Delaware counties eclipsed his suburban strength in practically every other swing state. Only suburbs in places like the Bay Area, Seattle, and New England voted more Democratic.

In total, Obama won the Philly suburbs by 15.56%. Combined with his landslide in the city itself, he came out of southeast Pennsylvania with a 682,392 vote margin. This meant that John McCain needed to win the rest of the state by 58.79%.

Photobucket

If Pennsylvania was like Missouri – if the remainder of the state voted strongly Republican – this might just have been possible. But Pennsylvania is not like Missouri; southwestern Pennsylvania used to be unchallenged Democratic territory, while Scranton, Erie, and the Lehigh Valley all lean Democratic. John McCain thus lost the state by double-digits.  His only successes occurred in southwestern Pennsylvania, which is reddening almost as quickly as the southeast is bluing.

Analyzing Swing States: Pennsylvania, Part 2.5

This is part of an analysis of the swing state Pennsylvania. Part three can be found here.

(A note: There will be a lot of maps in this post.)

Philadelphia: Precinct Results

My first post on the swing state Pennsylvania focused on the city Philadelphia, an incredibly Democratic city. At the time, I looked for detailed ward and precinct results but was unable to find any. Recently, however, I have come across a website which maps Philadelphia precinct results across a whole range of elections; it is a literal gold mine. This offers the opportunity to substantially deepen the previous analysis.

Below is a map, derived from the website, of the 2008 presidential election in Philadelphia (by precinct!)

Photobucket

An analysis of this result below.

The legend ranges from President Barack Obama’s weakest precinct (25% of the vote) to his strongest (literally every single person voted for him). In total, Mr. Obama won 83.00% of the county’s vote – an amazingly high figure. For reference, below is a map of Philadelphia’s black population.

Photobucket

There is, of course, a distinct parallel between the two demographic maps; blacks vote heavily Democratic and will continue to do so in the foreseeable future.

For decades, the city Philadelphia has trended Democratic. In percentage terms, its Democratic vote has increased for the past seven consecutive elections. In 1992, for example, former President Bill Clinton won 68.16% of the county. A comparison to Obama’s performance is revealing:

Photobucket

If there is any consolation for Republicans in all this, it is northeast (and parts of south) Philadelphia. Notice that in both maps above, Mr. Clinton and Mr. Obama perform distinctly worse here. This area of the city is populated mostly by white Catholics and Jews, although white flight has weakened their numbers. Nevertheless, northeast Philadelphia remains far whiter than the rest of the city, and as assimilated Catholics lose their traditional Democratic loyalties, Republicans have been gradually improving their percentages. John McCain actually did better than Bush in parts Northeast Philadelphia, supported by voters uncomfortable with Barack Obama’s race.

The above map hides this trend; many northeast Philadelphia voters cast their ballots for Ross Perot in 1992, so the Democratic percentage vote was artificially low that year (minority voters, on the other hand, generally did not vote for Mr. Perot). Comparing the Republican vote is more useful:

Photobucket

In general, Senator John McCain (who won 16.33% of the vote) does worse than former President George H.W. Bush (who won 20.19%). In the northeast, however, the opposite trend occurs. The shift is gradual and slow – not like West Virginia’s rapid red turn – but enough to be noticeable.

Under perfect conditions, growing Republican strength might result in something like this:

Photobucket

This is Secretary of State Hillary Clinton’s performance during the Pennsylvania primary. The senator won a respectable 34.80% of Philadelphia’s vote, fueled by support amongst white Catholics in the northeast. As evident in the map, the city contained extensive polarization; the majority of precincts gave over 70% of the vote to one candidate. In effect, Philadelphia split into two different blocs.

To be clear, Republicans will have a very difficult time achieving a result like this. It would take a momentous change for white Catholics to cast more than 70% of their ballots for Republicans. If this happened, moreover, winning Philadelphia would be the least of Democratic worries.

The other possibility would be for Republicans to improve their percentage amongst African-Americans. Statistically, 90+% support for any party seems untenable over a long period of time. Republicans, however, do not appear anywhere close to achieving this goal. The fact that they are more likely to reach 60% support amongst white Catholics than 15% support amongst blacks says a lot about the state of the Republican Party (and the state of America, too).

Analyzing Swing States: Pennsylvania, Part 2

This is the second part of a series of posts analyzing the swing state Pennsylvania. The next part can be found here.

Like Florida, and unlike Ohio, Pennsylvania’s political geography can be divided into three. The industrial southwest is reddening, the populous southeast is bluing, and Pennsyltucky remains, as James Carville memorably described it, “Alabama without the blacks.” (Actually, Pennsyltucky is a fair bit less conservative.)

The following section will concentrate on Philadelphia, the region upon which Democrats draw the most votes.



Philadelphia the City

Although cities always vote Democratic, different cities contain different political characteristics. Not all big cities are liberal (see Houston, Phoenix), nor are all liberal cities are big (see San Francisco, Boulder).

Fortunately for Democrats, Philadelphia is both America’s sixth largest city and one in which four out of five inhabitants regularly choose the Democrat. It is, moreover, a city which has become bluer for eight straight elections.

(A note: All my statistics are taken from http://www.uselectionatlas.org/)

Photobucket

More below.

Philadelphia’s decades-long movement towards Democrats has corresponded with six decades of population decline; white flight has gradually weeded out Republican voters. Machine politics – characterized by such practices as street money – continues to play a major role in elections.

Demographics underlie Democratic strength in the city (as they do throughout American cities). A full 44.8% of the city’s population is black, a heavily Democratic voting bloc. Latinos (another Democratic voting bloc), while fewer than elsewhere, comprise a solid 11.8% of Philadelphia.

A large majority of Philadelphia’s white voters must vote Democratic, too. In 2008 Obama took 83% of the vote, in a city whose non-Hispanic white population was 39.0% according to the census. Assuming minority turn-out proportional to their actual population, and assuming every single non-white person voted Democratic, then at a minimum, 56.4% of Philadelphia whites supported Obama. Under a more realistic assumption (e.g. 90% non-whites voting Democratic), 72.08% of Philadelphia whites would be supporting Obama. (The equation to get this is simple: 83.01 = 0.90*61.00 + x*39.00).

Philadelphia’s white vote revolves around two factors: liberal whites moving in through gentrification, and long-standing white ethnic communities. The former voting group – often young, single, and gay or gay-friendly – is liberal by orientation; the latter group, a consequence of long-gone anti-Catholic sentiment, still votes Democratic on economic issues but is slowly treading Republican.

All in all, Philadelphia’s existence constitutes an enormous advantage for Democrats. For the past three presidential elections, it has been around 60% more Democratic than the nation as a whole. If George W. Bush had won 80% of the vote in 2008 (and John Kerry had won 20% of the vote), he still would have lost Philadelphia by 3.60%. That is a shocking (and sad) statistic. As long as Republicans keep on losing the city by 4-1 margins, they’ll have a very difficult time winning Pennsylvania as a whole.

Photobucket

Finally, notice how – for the first time in history – Philadelphia’s suburbs now lean Democratic. That shift, which I will cover next, should disturb even the most confident Republican.

Philly Mayoral Primary Open Thread

Like David, I don’t have a moose in this race, but hey, it’s an election–and if one of either Rep. Chaka Fattah or Rep. Bob Brady can pull off an upset win, we’d be dealing with yet another House vacancy and special election this year.  However, the odds of such a scenario happening appear to be long.  For more coverage, results, and analysis check out Young Philly Politics and the Philadelphia Inquirer.


UPDATE (David): It’s Nutter. I wonder if retaking the majority made the mayoralty less appealing to Fattah and Brady.
