It looks like Ace is getting on the Paul Ryan for President bandwagon.
I think Ryan is going to realize that no one, no one will run on his plan, because no one else can. They will give it, at best, weak-tea "I'll look at it" statements like Boehner does ("I'm not wedded to it").
This is not purely a matter of courage. Ryan has spent eight or ten years becoming an expert on budget and entitlements and fiscal policy. No one else can simply become an expert in a few short months.
No one can answer the questions he can. He's looked at them all and has answers for them.
