Rep. Mark Kirk (R-Ill.) and Treasurer Alexi Giannoulias (D) are neck-and-neck in the race to permanently replace President Obama in the Senate, according to a new automated poll from Rasmussen (Oct. 14, 500 LV, MoE +/- 4.5%).

Giannoulias holds a small lead in the money race with more than $2.4 million in the bank as of the end of September, while Kirk announced raking in $1.6 million in the 3rd quarter to bring his cash on hand to $2.3 million.

Also tested against Kirk were Democrats Cheryle Jackson, a former top aide to Rod Blagojevich, and Chicago Inspector General David Hoffman.
