I don't generally believe in political litmus tests, except for issues like the right to keep and bear arms. I simply could never vote for Mitt Romney based on his open betrayal of the Second Amendment. If this is the best the GOP establishment has to offer, then let Obama have his second term.
I've had enough of the establishment candidates from BOTH parties.
If Romney wins the GOP nomination, then it just won't matter who wins the general election.
If Romney is the GOP nominee, then third party/TEA party/independent will be the only way to go, and let the chips fall where they may, and let the gutless establishment gnashing of teeth begin.
Romney's authoritarian socialist stench is simply too much for this conservative libertarian to hold his nose for...
Romney is the only potential Republican candidate that I simply can not vote for. I would rather fight Obama for 4 more years than put up with Mitt Romney.
Bears repeating, imho. I will not vote for someone with an anti-Constitutional track record. No Mitt, No way!
The RKBA is the only litmus test needed. If they're wrong on that, then they shouldn't be in public office....period.
