Illinois Senate: Kirk (R), Giannoulias (D) Remain in Tight Race

Tuesday, October 05, 2010

The Illinois race for U.S. Senate between Republican Mark Kirk and Democrat Alexi Giannoulias is still neck-and-neck.

The latest Rasmussen Reports statewide telephone survey of Likely Voters shows Kirk picking up 45% of the vote, while Giannoulias earns 41% support. Four percent (4%) back Green Party candidate LeAlan Jones. Another five percent (5%) prefer some other candidate in the race, and six percent (6%) are undecided.

The race is little changed from  two weeks ago, when Kirk posted a 44% to 41% lead over Giannoulias and Jones has four percent (4%) support. 

The race is still a Toss-Up in the Rasmussen Reports Election 2010 Senate Balance of Power rankings.

Kirk and Giannoulias have now run within four points or less of each other in eight surveys since early June.
