IL-Sen: PPP’s Switch to LV Model Still Yields a Slim Giannoulias Lead

Public Policy Polling (8/14-15, likely voters, 6/12-13 in parens):

Alexi Giannoulias (D): 37 (31)

Mark Kirk (R): 35 (30)

LeAlan Jones (G): 9 (14)

Undecided: 19 (24)

(MoE: ±4.1%)

As you know, PPP has made the Great Schlep to a likely voter model from their earlier voter model, which was lightly-screened and tastefully seasoned with a patented formula of herbs and spices. (God, I’m hungry.) In terms of sample composition, the results have, predictably, been pretty ugly for Democrats. In this poll, for instance, the likely voter universe favored Obama over McCain by only 9% in the 2008 election — a big jump from the 19% Obama margin that PPP found in their poll from June, and from the actual election day margin of 26%.

However, unlike their Pennsylvania Senate poll, Democrat Alexi Giannoulias is still holding onto a very slim lead. Some more color, from Tom:

Kirk does have a big lead with independents, 36-20. But you can’t win as a Republican in Illinois without winning over a fair number of Democratic voters and Kirk just isn’t doing that right now. He’s getting only 5%. Kirk’s getting 74% of the Republican vote while Giannoulias is getting 72% of the Democratic vote and it’s going to be very hard for Kirk to win unless the party unity gap ends up being bigger than that.

Both candidates continue to be very unpopular. Giannoulias’ favorability is 26/42 and Kirk’s is 26/34. Independents have a negative opinion of both of them, and each of them is viewed more unfavorably by voters of the opposite party than they are favorably by their own party base. Only 51% of Democrats have a favorable opinion of Giannoulias and just 49% of Republicans have a favorable opinion of Kirk so neither contender is doing much to fire up even their partisans.

Battle of the weak, indeed.
