I guess you haven't been watching the debates.
Obama is the #1 target.
Every one of them slam him on every issue.
Keep in mind, with unemployment this high & 3 out of 4 people not happy with the direction we are going, if the republicans aren't leading now, when?
The economy is getting better, slowly, recent news supports that. If its near 8% Obama by Autumn he can really make a good case for re-election.
