I'll vote against O whatever happens. But I agree, if Romney is the best this party has to offer, I'm in the wrong party.
I've said several times, if Romney is the nominee and loses to O, the party breaks. And if he wins, it may break anyway.
Either way, I personally am in the wrong party and plan to do something about it.
Ronald Reagan was a Democrat. He didn't leave the party, the party left him. Likewise today with the Republican party.
