JEB Bush and Karl Rove, his Strategies group.

The first fundraiser was at the Crawford Ranch. All the non-trumpers came and gave Ron the maximum donation, the reason you see him throwing money around.

But he is running out of money and those people cannot donate again until the general election as they are maxed out! He must now rely on the smaller donations and grassroots, the group of people he does not have.

He's finished. He's been finished! JEB keeps telling him Trump will go to jail and to wait.

But the short answer is that he got his money from the Bush's.
