When are we going to hear about the Bush’s choosing Clinton over Trump? After all the Bush’s greased the skids for the first Clinton and Obama and 28 years of unconstitutional Leftist government expansion and activity. The Bushes and much of the GOP are simply warmed-over DNC folks.
The worst mistake Reagan ever made was making George HW his VP.
The Bushes are North Eastern country club Liberals, and they never had any business getting into power in the first place.
They won't openly endorse Hillary, because to do so would be to admit that the "choice" between Democratic and Republican establishments is no choice at all. It's important to maintain the charade that there's a real ideological divide between the Clinton-type Democrats and Bush Republicans, when they are really one and the same.
As I said earlier, the Bushes and their political team (Rove, the neoconservatives, etc) will help Clinton by pulling whatever strings they can to sabotage Trump in the general election. They'll just do it behind the scenes.
