Missouri Going Deep Red

It's hard to believe that the state that produced Harry Truman is now represented by Claire McCaskill. But not for long.

Sen. Claire McCaskill (D-Mo.) trails all three of her potential Republican rivals, according to a new survey conducted for two Missouri news outlets, cementing her status as this cycle’s most vulnerable incumbent.

Businessman John Brunner (R) holds the largest advantage over McCaskill, leading by a 52 perent to 41 percent margin. Former state Treasurer Sarah Steelman (R) leads by a 49 percent to 41 percent margin. And Rep. Todd Akin (R) leads by a 49 percent to 44 percent margin.

McCaskill’s big problems come among independent voters . She scores just 40 percent among independents against Akin, and she’s mired in the mid-30s when she’s matched up with Brunner and Steelman.
