My guess is that Trump is paving the road for Bush. Trump will drop out before the election and praise Bush (which he is already doing if you listen carefully to what he is saying). Bush will despite being outsmarted by a pigeon will start looking like a regular joe and not utterly useless. My guess is that Bush family is offering Trump something and that this was planned for a long time, many years ago. In the end Bush will win the election against Clinton. Though Clinton may not be the president US needs, Bush family has and will never steer the world or the US on a progressive path. They are in it for the money like many else, but they are far more opportunistic than most. Hopefully they won't ruin the country...
