You can't win the GOP nomination, how will you win nationally ?
Where will you find your voters ?
What are you going to do, start a Tea Party? How's that worked out for one-and-done Allen West or various senate candidates like Akin, Mourdock, O'Donnell and others... easy wins that were thrown away?
But wait, you don't even want a real Tea Party because the actual Tea Party movement is SILENT on social issues.
Ha, the GOP's been running loser candidates (McCain and Romney), so if the GOP's "best winners" are that much of losers what does that say about the party?
You forget that Romney wasn't offered, he was actively pushed. Remember the fiascoes at the RNC? Remember the primaries where Romney was declared winner, with a later 'we were wrong'? Remember the Ron Paul supporters winning delegates through some good rules-lawyering, only to be denied when the results came out?
