Good letter. There are probably a thousand conservative orgs across America who would have joined in signing, if asked.
We would all sign this and a petition for him to quit the primary races and throw his support to the best candidate that will be able to beat Her Highness or BO. If he wasn't in a state where there is a Dem guv, I could see him, if a Pub wins the Presidency, becoming SecDef. His gruffness and ego would work well in blasting our enemies. As Prez, I would be worried about the rubber room for him!
