This is from Hot Air’s comments:

For the governors, Walker, Jindal, and Perry. From Congress, Paul and Cruz. I’m sure there’ll be at least one unconventional outsider type who gets in(maybe Bolton?). That’s a pretty solid field actually. Honestly we don’t need a dozen candidates up there. It’s quality, not quantity.

I assume he means ‘Solid from the perspective of being able to win the GOP nod”, not the general election.
