Obama has been in campaign mode since 2007. He never stops so no one should be surprised by this.
What the Republicans have failed to do is present an understandable plan of their own. They say we need to cut spending, but what spending? They say we need to grow the economy but how? When you've got 47% of the population that is desperate you better have a better alternative they can believe in before you ask them to let go of the "Flotation Device" they're clinging to and grab for yours. The Republicans haven't done this. Without specifics people are always going to Dance With The Devil They Know until something better comes along. Right now that's still Obama. It's not that people love him but for now he's all they've got.
