I wouldn’t cast a vote for Jeb Bush if he were the last ded-gum republican on earth.
If he makes it to the general, I will be voting Libertarian/Constitution party...whatever, but it won’t be for the Bush “dynasty”. Now way, no how.
A choice between Jeb and Hillary is no choice at all, as far as I'm concerned. It's like being given a choice between watching your house burned to the ground vs. smashed to bits with a wrecking ball.
