Trump is a liberal Republican, but he’s not a Bush Crime Family (establishment) Republican.
Liberal Republicans in 1940 didn’t feel about Willkie the way their descendants today feel about Trump.
Ask yourself, "Why?"
If, and when you do, the answer will become quite clear to you. Here's a small hint. Donald Trump had no real need to do any of this, on a personal level. It isn't making him more money, and in fact, right now, is costing him money (although he is being quite frugal about his campaign spending.) So, why go through this?
Some here say that he is doing it to enable the election of Hillary Clinton, which is utter hogwash. If he wanted *that* particular outcome, the best way to have achieved it was to literally, do nothing, stay on the sidelines, not enter the race at all. The GOP establishment had concocted an ingenious plan to get Jeb Bush nominated, with only approximately 20% of the vote. Bush would have then been 'sacrificed' to the other party, just as McCain, and Romney were in 2008, and 2012, respectively.
But, what does Mr. Trump do? He enters the race, and before the first votes are even held, lays complete and total waste to the carefully crafted plan the GOP 'elite' had devised. They have not recovered *YET* from that debacle, thus the fear, loathing, and hate from that quarter. A year and a half of conspiring and planning to rig this election to a predetermined outcome totally trashed in 6 months.
Mr. Trump may, no, let's be honest here, is not, nor never has been what most folks here could rightfully call a conservative, but, at the end of the day, he *is* an unashamed American, and at heart, a patriot. I can live with that...
