Any of them could break the pledge. But I don’t think Bush would. Just not a very Bush thing to do. I really can’t think of any of the 17 that seem likely to do that.

16 now. Maybe Perry is going third Party.

I think Perry could run third party and it would make no difference.

But if he couldn't afford to continue in the primary, how could he afford to run third party?

I doubt Rand Paul would run third party, but maybe he could. Ron Paul could run third party. But probably only if Rand wins the primary.
