The question is...will the Tea Party radical base believe him? He's taken both sides of every issue over the past several years.
The Tea party folks aren't radical at all. They are just main stream average working people fed up with overreaching government.
The problem with the current crop of Liberals / progressives / Democrats is this. Anything or anyone you disagree with, you label extreme or radical. People aren't buying it any more. Sure, 10 to 15% of the hard core left wing political hacks will, but no one pay any attention to them anyway.
