Money and Fundraising (more than anyone else) did nothing for Jeb Bush it seems. 
that was the primary. there was no stopping trump. the low-education nascar fans anointed trump the winner early on.
There aren't any swing voters in the primaries. the extreme decides.
Trump has to win the middle 6% that decide every election. TV time during "Big Brother" or "Dancing with the stars" showing Trump dropping F bombs and imitating the handicapped are very effective.
In the polls trump's doing well, he's still at 41 or 42%. Hilary's bouncing between 48 and 38 in polls. Trump's pretty solid. I don't see anything he can do, any moves, to magically win 49 or 50% of the population. The 7% of the nation that thinks he's an idiot aren't going to change. They would rather have the nation in the hands of a highly capable criminal (hilary) than a wide-eyed obnoxious dude who might make us great, or might start WW3.
