From the PPP blog (with more information below the fold):
The Illinois Senate race continues to be very close, but because Mark Kirk is doing a better job of consolidating his base than Alexi Giannoulias is he’s taken a small lead after trailing by 2 points on PPP’s previous two polls of the race. Kirk is ahead 40-36 with Green Party candidate LeAlan Jones at 8% and Libertarian Mike Labno geting 3%…
A big factor to watch moving forward is whether Jones, the Green Party candidate, can maintain his support in the final 5 weeks as it becomes more clear that votes for him could push this race into the Republican column. On one hand Jones’ voters strongly dislike Giannoulias- 56% see him unfavorably to only 21% with a positive opinion. On the other hand they are a strongly Democratic leaning lot with 65% of them having voted for Barack Obama to only 28% who were McCain voters. If Jones fades Giannoulias will gain but if his support remains steady that’s going to be a big plus for Kirk.
In the poll itself, Jones picks up 7 percent of Democrats, 6 percent of Republicans, and 13 percent of independents. Labno gets 2 percent from each major party, with 5 percent of independents. Jones gets 5 percent support from African Americans, which is interesting, because in a previous poll where he had 14 percent support overall, he had 26 percent support from African Americans.
