Just my feeling on this. Obama is pissing off a whole bunch of Democrats and we seem to forget that little fact.
The tale will be told in 10 days.
Obama isn't even appealing to the middle class, he is making appeals to his fringe supporters, the youth vote, Unions, etc.
The State polls are showing Obama even with Romney so the Democrats will not be discouraged and vote, this is about the Senate, not the Presidency.
