He has. Obviously you never heard the reason why he became pro life for instance. Check it out. It’s a sobering story and to his credit Trump changed his mind. People should quit telling lies about it.
He absolutely seems to have changed. Most of his positions look to be Populist. Somewhere along the way he appears to have rejected the Elitism side of politics. I suppose once you get F.U. Money, you are freed from some of the shackles of the establishment -- and he most definitely has F.U. Money.
The political battleground has changed drastically in the last 20-30 years. It is now Elitist vs. Populist. That is why you see so many Republicans acting so inexplicably oddly. It is also why Trump is so popular, with crossover appeal.
The Elitists have very VERY bad plans for us. Erasure of nations, removal of all defensive weaponry from the populace, thought-control (literally), and gross depopulation (probably on the birth side, I think they learned from Hitler / Stalin / Pol Pot how bad it goes on the other side).
I freely admit I could be wrong. This could be the best acting job since Heath Ledger's "Joker". This is a bit of a dice-throw for me. While I would prefer Cruz, Trump has a large lead. So I will toss the dice on Trump. Best to toss the dice, than to submit to the Globalist/Elitist world paradigm.
The thing that informs me that it is likely not an act, is the response of the Elitists. They threw Jeb, Rubio, and Carson at us. They tried to smear Trump in every way. They are planning to split us with Cruz by inflating his polls.
Those are not the actions of a people who want Trump to be the nominee.
