House Dem voter attrition in 2010

Conventional wisdom has it that turnout is the key issue in midterm elections. In view of that, how well did individual House Democrats do in convincing their 2008 voters to back them again in 2010? This post looks only at total votes, not margin of victory or defeat. Members who did not run in 2008 (Bill Owens, Mark Critz, Scott Murphy) or who had no Republican opponent in 2008 are excluded. The remaining 198 members’ average 2010 vote was just 61.2% of their 2008 vote. Curiously the median was also 61.2%. These folks managed to retain at least 70% of their 2008 vote:

Here we have 24 reps from the west coast vote-by-mail states of California, Oregon, and Washington and 9 from the rest of the country. David Wu and Peter DeFazio went unopposed (at least by Republicans) in 2008 and Brian Baird retired, so every eligible rep from Oregon and Washington shows up on this list. We also see a lot of people from completely uncompetitive districts. Nancy Pelosi and Jim McDermott put up nice numbers, a function of their dogged, relentless campaigning…heh. A function of most of their constituents being unwilling to consider voting for a Republican under any circumstances.

It would be more interesting to limit the list to people who actually faced a credible threat and thus had to run a serious campaign. As a first approximation, cut out anyone whose district is D+10 or better. Here’s the top 10:

rank rep   dist   2008       2010       retention pvi

1 Pingree   ME 1 205,629     166,196     80.8      8

2 Schrader OR 5 181,577     145,319     80.0      2

3 Giffords   AZ 8 179,629     138,280     77.0      -4

4 Titus       NV 3 165,912     127,168     76.6      2

5 Lujan       NM 3 161,292     120,048     74.4      7

6 Bright     AL 2 144,368     106,865     74.0      -16

7 Inslee     WA 1 233,780     172,642     73.8      9    

8 Dicks       WA 6 205,991     151,873     73.7      5

9 Tonko       NY 21 171,286    124,889     72.9      6

10 Himes       CT 4 158,475     115,351     72.8      5

8 of the 10 are in blue districts and 6 of these are D+5 or better. And then there’s Bobby Bright. Now for the bottom 10:

rank rep     dist     2008       2010 retention pvi

110 Grayson       FL 8 172,854    84,167 48.7 -2

111 Boyd               FL 2 216,804    105,211 48.5 -6

112 Childers       MS 1    185,959 89,388 48.1 -14

113 L Davis       TN 4 146,776    70,254 47.9 -13

114 Ortiz             TX 27 104,864    50,179 47.9 -2

115 C Edwards   TX 17    134,592 63,138 46.9 -20

116 Kosmas         FL 24 211,284    98,787 46.8 -4

117 Etheridge     NC 2 199,730   92,393 46.3 -2

118 C Gonzalez   TX 20 127,298    58,645 46.1 8

119 Taylor           MS 4 216,542    95,243 44.0 -20

9 of the 10 are in red districts, and 4 of those are really red. Charlie Gonzalez’ appearance on this list is  misleading as he was never in any trouble. He didn’t get his people out, but he didn’t need them. In any case, it’s understandably a lot harder for Dems to hold on to their presidential-year voters when a lot of them are normally inclined to vote red.

So the two basic rules appear to be: 1) People are more likely to vote in midterm elections when they can conveniently vote by mail, and 2) the bluer your district is, the less likely your voters are to swing against you in a red wave year. I did a simple regression analysis to compute members’ predicted retention based on the PVI of their districts and whether their state predominantly uses vote by mail. Using only the D+9 or lower district as the sample, each point of PVI increased retention by an average of about 0.25 percentage points and vote-by-mail increased it by an average of 7 points. The “diff” column shows the difference between actual retention and predicted retention. So here is the adjusted top 20 as measured by differential:

rank rep        dist    diff

1 Pingree     ME 1    19.6

2 Bright         AL 2    19.1

3 Giffords     AZ 8    18.9

4 Titus           NV 3    17.0

5 Lujan         NM 3    13.4

6 Schrader   OR 5    13.3

7 Himes         CT 4    12.3

8 Kratovil       MD 1    12.3

9 Tonko         NY 21    12.2

10 Perriello     VA 5    11.8

11 Sarbanes   MD 3    11.6

12 Arcuri           NY 24    10.0

13 Boswell       IA 3    9.6

14 Yarmuth       KY 3    9.0

15 Peters         MI 9    8.9

16 Courtney   CT 2    8.9

17 C Murphy   CT 5    8.8

18 Altmire       PA 4    7.2

19 Heinrich     NM 1    6.9

20 Boren         OK 2    6.8

And it’s still Chellie Pingree by a nose. Interestingly, the top 19 consists of 18 freshmen or sophomores and one Boswell. (Yep, the much-maligned Leonard Boswell arguably ran the best campaign of any House Dem with actual experience of serving in the minority.) This seems counterintuitive given that newer members have not had much time to build up goodwill and thus should be more vulnerable to losing support in a red wave year. Instead, it appears that these newer reps were used to having to scratch and claw for every vote and thus adapted more easily to an unfriendly environment than veteran reps who were used to winning easily did.

There was a big gap between #3 and #4 and an even bigger gap between #4 and #5. These four super-overachievers come from dissimilar districts and had dissimilar records and this time I don’t see a pattern:

Pingree was one of the few Dems to win by a bigger margin in 2010 than 2008, and this doesn’t appear to be any unobserved Maine-specific effect (Libby Mitchell coattails? heh) as Mike Michaud had a differential of just +4.8. This race did not get much attention, although it was considered competitive at one point. Was Pingree’s remarkable retention number a function of a sloppy campaign in 2008 or a brilliant one in 2010, or both?

Bright almost never voted with the Dems, but Gene Taylor didn’t either and Bright only retained 30% more of his 2008 vote than Taylor did! It still wasn’t enough to get him over the hump, but he came a lot closer than similarly situated dudes like Lincoln Davis, Chet Edwards, and Travis Childers.        

Gabrielle Giffords was the other red-district rep to make the unadjusted top 10. Her district is far more purple than Bright’s but she also took many more risks than he did, voting for TARP, the stimulus, cap and trade, health care, and financial reform. This did not appear to hurt her much with the Dems and swing voters who voted for her in 2008. Like Pingree, she got zero up-ballot help but unlike Pingree she just barely held her seat. Her voting record may have motivated the people who opposed her in 2008 to stick around and pull the lever for that megatool Jesse Kelly.

Unlike the top 3, Dina Titus got some indirect help in the form of Harry Reid’s fearsome operation. Titus probably deserves some credit for her strong showing, though. Shelly Berkley isn’t a perfect comparison (much higher baseline Dem vote but also a much less threatening opponent) and with a D+10 district just missed the regression sample, but her differential would have been +4.9, and 12 points is a big spread in any case.

Here is the adjusted bottom 20:

rank rep             dist          diff

100 B Miller           NC 13    -8.0

101 Nye                     VA 2    -8.1

102 Loretta Sanchez CA 47    -8.1

103 Space               OH 18    -8.1

104 Cuellar           TX 28    -8.3

105 Doggett           TX 25    -8.6

106 Boyd                 FL 2    -9.0

107 Taylor           MS 4    -9.9

108 Donnelly           IN 2    -9.9

109 Grayson           FL 8    -9.9

110 Filner             CA 51    -10.1

111 Hinojosa             TX 15     -10.2

112 Ortiz               TX 27    -10.8

113 Pallone           NJ 6    -11.3

114 Kosmas           FL 24    -11.3

115 Visclosky         IN 1    -11.6

116 Carnahan       MO 3    -11.9

117 Etheridge         NC 2    -12.4

118 C Gonzalez       TX 20    -15.2

119 Costa               CA 20    -17.8

There may be some unobserved variation related to demographics or state election laws, as the only state to put a rep in both the top 20 and the bottom 20 was Virginia. Glenn Nye managed to retain 20% less of his 2008 vote than Tom Perriello did despite voting with the Dems less often. Texas in particular was a sea of apathy for Dems, as the best performer was actually Chet Edwards at -6.9! That said, Bob Etheridge’s failures are his own, not North Carolina’s. Heath Shuler managed a +4.6 differential.

If you rightly ignore Gonzalez who won by 29 points, Jim Costa turned in the worst performance by a country mile. It’s true that his district is young and poor and heavily Hispanic, but so is Raul Grijalva’s, and Grijalva had a +3.6 differential without the benefit of vote by mail! (Grijalva’s big mouth probably ran up Ruth McClung’s vote total as opposed to depressing his own, as his margin of defeat was worse than even the hopeless Rodney Glassman’s in some counties.) We’ll see if Costa takes his narrow escape as a wake-up call, as commission redistricting is likely to put him in a less friendly district.

Just eyeballing the data, it appears that richer districts generally had more retention than poorer ones (note the 3 Connecticut dudes in the top 20 and the many south Texans in the bottom 20) so I may rerun the numbers once I find enough time to enter the median income of all the districts.

Some conclusions: Chellie Pingree and Leonard Boswell are underrated. Don’t be surprised to see Bobby Bright, Dina Titus, Frank Kratovil, Tom Perriello, and/or Michael Arcuri resurface. Keep an eye on Ben Lujan. Russ Carnahan and especially Jim Costa need to step it up. It may be premature to speculate about Gabrielle Giffords’ future (early signs are good), but she was a beast as of 2010. Vote by mail is great. The Texas Dems’ 2010 turnout was uglier than the Texas Longhorns’ 2010 offense.

Thoughts? (How do you post clean tables from spreadsheets? I tried saving them as PDFs but was unable to convert them to photos.)    

By what margin will Bob Shamansky win?

  1. Pingree had a much tougher opponent in 2008 than she did in 2010 and had to deal with the epic fail of Tom Allen up-ballot (which was probably a bigger drag than Libby Mitchell because many more people voted for Susan Collins then for Monsieur LePage).

    It’s funny that Giffords ended up right up there with representatives in states where you can vote by mail, because the Giffords campaign and the Pima County Democratic party really aggressively pushed vote by mail registration. More than anything that’s probably why she’s still in congress. Now if only Maricopa County Democrats would get with the program we could be in business in this state.

  2. Could really learn something from Boswell’s performance in 2010, especially since neither of them had had credible opponents last year and each had the luxury of running in districts that have been Democratic in every presidential election since 1988.

    Peters really was impressive this last year, too, with Bernero winning only 36% at the top of the ticket. Peters outperformed Bernero 13 points and Raczkowski underperformed Synder 15 points in the 9th. Granted, ever Democratic incumbent or candidate in competitive races in Michigan did better then Bernero, and Raczkowski was a relatively weak nominee, but Peters was the only Dem in a competitive congressional race in Michigan to win.

  3. In 2008, she had a major challenger from the left (Cindy Sheehan) getting 17% of the vote.  You’re ignoring non-competitive districts already here, but if you adjust for this Pelosi’s numbers aren’t that special.
