I expect he will win.

I don't want to be overly pessimistic here because its not over till election day, and the economy sucks.
But Romney was able to take out his ABBMR opponents one by one because they were busy fighting each other and so Karl Rove Crossroads and similar groups could nuke each one in the clear at that time with TV ads, ads that Republicans were receptive to. Romney just had to play act conservative.
In this case it is NOW one against one and the TVs will be saturated with ads so they will not have the same effect as then because people will tune them out being so many as noise.
See how Obama gives no interviews but Romney and Ryan do? See how Romney accepted all MSM moderators at the debates? There is a reason why R+R put up with this.
