Barring a total economic collapse obama will make road kill out of Romney as well.
Romney brings out about as much enthusiasm as a strangulated hernia for the conservative base.
With Romney as the nominee you will lose 5-10% of the conservative base and that will cost the GOP liberals the election.
There is historic precedent for this. John McCain most recently comes to mind. BUT, the “STUPID PARTY” apparently wants to throw another election and lose this one as well, so what can you say. Oh well....see you in the camps.
