I agree with your sentiments, and your final conclusion. However he could win the primary, just not the general.
The problem we have is that we get one moderate and a bunch of conservatives running. Our vote gets split and our guys & gals tear each other up. The lone moderate gets all the establishment votes and is above the foray.
Maybe what we need to do is reverse the situation, encourage Bush, Christy, Romney, etc to run so they split their vote for a change.
Just a thought.
I’m not so sure Jeb could win the primary.
People are sick and tired of the GOP-e and the Bushes.
