She is courting the women's vote, especially suburban women (read Kansas City and St. Louis). If she succeeds, she will not be beaten.
19th Amendment was a bad idea bump...
Her votes are out of step with the Conservative majority in Missouri, and always have been. She won a fluke upset over Sen. Talent in 2006 solely because it was an anti-GOP year and was headed towards a likely defeat in ‘12 against any GOP nominee.
She took a calculated risk by trying to get the nominee she wanted to run against, but it was done because she thought Todd Akin (not Aiken) would be too Conservative. He wasn’t, and he had a lead from the moment he was nominated. Had he not made his ill-advised remarks (that no one could’ve predicted), it’s likely she would’ve lost by upwards of 15%. She isn’t suddenly going to become more popular between now and 2018, and there will likely be a host of Republicans lining up to take her down.
Her only possible hope is to have a RINO Presidency take office in 2017 to run against with its predictable incompetence (to wit: if Willard had won in ‘12, we’d be facing disastrous anti-GOP midterms this year), but if the Dems retain it, she is finished, and so will be the low-hanging fruit that dodged the ‘12 defeats because of terrible (mostly RINO establishment) opponents (which was, in fact, the real cause of the GOP’s failure to win the Senate, the more than 10 races, not the convenient scapegoats of Akin & Mourdock).
