Outraged their candidate is showing a double-digit lead? Has to be a first.

Via The Hill:

Rep. Todd Akin (R-Mo.) trails Sen. Claire McCaskill (D-Mo.) by double digits in their Missouri Senate race, according to a survey released Thursday from conservative polling outlet Rasmussen.

McCaskill leads with 48 percent support, while Akin has 38 percent.

A previous survey from liberal-leaning Public Policy Polling, conducted and released only one day after Akin’s controversial “legitimate rape” remark, showed the Missouri congressman with a 44 to 43 percent lead.

The Rasmussen result marks an astonishing drop for Akin and indicates Republicans’ worst fears could come true — that Akin’s candidacy will cost them a Senate seat. Previous polls showed McCaskill was vulnerable and Akin was leading her. […]

And Democrats were quick to push back against the poll, saying Rasmussen has a conservative bias and is in cahoots with GOP party leadership in trying to pressure Akin out of the race.

“Everyone knows that Rasmussen is a tool of the Republican establishment in Washington,” Democratic Senatorial Campaign Committee press secretary Shripal Shah told The Hill.

A McCaskill campaign aide added that “it’s just not inline with what we’re seeing in our internal polling.”

“There’s a concerted [GOP] effort to get Todd Akin to bow out,” he said. “So it’s quite a coincidence that this poll came out right after someone in his campaign said he would reevaluate if he was down by 7 to 9 percent…we were just out [polling] in the field yesterday and it showed we’re in a dead heat.”
