Missouri Democratic Senator Claire McCaskill is closing with a big lead, according to a new poll from SurveyUSA and commissioned by four in-state TV stations. McCaskill gets 51 percent of the total, GOP Rep. Todd Akin gets 36 percent, and Libertarian candidate Jonathan Dine sees 8 percent. The same poll shows Republican presidential candidate Mitt Romney winning by 7 points, 50 percent to President Obama's 43 percent.
Akin's campaign has been steeped in controversy since he made his "legitmate rape" comments back in August.
The PollTracker Average of the race shows McCaskill with a solid lead in the final days.
