In February, a Research 2000/Daily Kos poll showed U.S. Senate candidate Alexi Giannoulias leading Republican Mark Kirk by seven points while Gov. Pat Quinn edged challenger Bill Brady by fifteen points. Two-and-a-half months later, a new Research 2000 survey shows both Democratic candidates behind by three. Here are the toplines (with the February results in parentheses):
Giannoulias: 38 (43)
Kirk: 41 (36)
Quinn: 35 (47)
Brady 39 (32)
The survey shows that both Giannoulias' and Quinn's favorability has slipped in the intervening period, while the Republicans' figures have stayed more-or-less the same.
The poll was conducted between May 3 and May 5. It has a margin of error of +/- 4 percentage points.
UPDATE (1:30 p.m., 6/29/2010): The DailyKos, who commissioned this poll, has renounced all of their polling conducted through Research 2000, including this survey.
