Once Rick Perry (and Gov Palin before him) was slammed and denegrated on FR, I could see quite clearly that principles meant nothing. So the answer to your question is no.
As another FReeper says in his tagline: ‘Our founding fathers would have been shooting by now’ (not a quote but close enough).
NOT VOTING IS NOT AN OPTION.
You don't get to make that decision for anyone. People vote or not according to their conscience or circumstance - not yours.
There is only one candidate - Newt in the primary. And, hopefully, in the general or 3rd party or write in.
Mitt doesn't belong in the GOP race, he's a liberal and his record proves. NO voter with standards will vote for him only a lib with buyers remorse. Then they will have it again in another four.
