The Senate Swing

A month is a long time in politics. Silver:

The Democrats’ chances of controlling the Senate have increased to 79 percent in the forecast, up from 70 percent on Tuesday. Had we run the model a month ago, based on polls through Aug. 19, the Democrats’ chances of maintaining Senate control would have been listed at just 39 percent.

Tommy Thompson has just lost the lead in the Wisconsin Senate race to Tammy Baldwyn. McCaskill now edges Akin, Warren is in a much tighter race with Brown; and in Indiana, Democrat Donnelly has edged ever-so-slightly ahead of Mourdock.

Holy Ga-Ga. What the H-E-double-hockey-sticks is going on out there? And Maddow just beat O'Reilly in the critical demo two nights in a row.
