“So your argument is completely dependent on the future event of Palin supporting Crist.”
What would you do if she decided not to run but campaigns for Romney throughout the primaries instead? Personally I hope she is our next POTUS.....at this point. This does not mean that in my eyes she walks on water and defecates gold bricks however.
If she campaigns for Romney, I will do more than just put her on probation like when she first came out with support of McCain. I will probably be done with her.
But I don’t see any sign she will do it. Her support of McCain is best explained as upholding a promise.
