Your trying to frame the argument as if given a real choice I, and may others, would chose Romney over Palin. Probably most conservatives would still chose Palin. Third party bids are simply not a real choice.
I don't follow your logic at all, but there you have it. Again--that kind of thinking is how we got where we are.
It just sounds like your one of these hard heads that just can't accept that the US has a 2 party system. We have a winner take all set up and no option for coalition government. I'd have thought you could look at the last hundred plus years of history and see pretty plainly that 3rd party bids don't succeed and only serve as spoilers.
Not only would I not vote for Palin if she ran a dopey 3rd party vanity bid, I would pretty much lose all respect for her considering she's be essentially helping Hussein win a 2nd term.
