I have heard Dick Morris (ok, ok, I know...) explain this dynamic as well. When Morris was working for Clinton on his re-election for governor in Arkansas, he got polling data two days before the election that Clinton has slipped below 50%. It was the middle of the night. He got over to the governors mansion, dragged Clinton out of bed and the two went over to the recording studio and cut ads in the middle of the night to address the issue. The ads worked and Slick was reelected.
The 12% undecided number is huge. If Obama goes into the election with it, he loses.
Obama still has his 30 minut three network infomercial.
If this interview goes viral, it is going to force him to address his socialism in that infomercial.
He is still pushing the big lie about the 95% tax cut.
The infomercial is a preplanned 30 minute slick willie late night recording.
