Walker's off my list. He's just another Chamber of Commerce water boy with no DC voting record. I trust him about as much as I'd trust Mitt Romney, Jeb Bush, or Chris Christie. I think you're a bit harsh with that assessment.
Scott is a personal friend of mine. I like him a lot, but much prefer Ted Cruz.
I don't think Walker is a Chamber waterboy, but I do think he tries too hard to thread the needle in his politics when blunt force might be the better option.
He might be a nice guy, but his latest statements enable the invasion of the US. For me, that's a stopper. Any politician who does not realize we cannot absorb the non-citizens who are in the US just does not understand the crisis we face. And a stadium scam? If it were a good deal a public corporation would emerge and sell stock to fund it.
I like Cruz, too, but wonder a bit about him on foreign policy expertise and where he is on the financial mess in the US. I wish Jeff Sessions were running. Jindal is beginning to emerge as a strong voice.
