Akin’s ‘Macaca moment’ could flip the Senate race (Originally posted on Yahoo!'s "The Signal" Blog)

Missouri Republican Rep. Todd Akin woke up Sunday morning with a 65 percent chance of unseating incumbent Democratic Sen. Claire McCaskill in the upcoming Senate race. By the end of the day, after facing a torrent of criticism over his claim that women rarely get pregnant as a result of "legitimate rape," the tables had turned: Our real-time predictions now give McCaskill a 60 percent chance of retaining her seat.

It is not too soon to speculate that this could be the 2012 variety of George Allen's 2006 "Macaca moment," which was instrumental in the incumbent senator's defeat. That narrow loss, as well as several others, cost the Republicans control of the Senate by one seat that year.

The Senate hangs in an equally fine balance this year. Before Akin's odds went south, the Republicans were on track to control 50 seats to the Democrats' 49, plus one independent. While that figure will almost certainly wobble between now and November, it is eminently possible that one seat will make the difference.
