Yep.Trump doesn't believe a single thing he says, just go watch his past tapes and views on issues. He completely destroyed the GOP in a matter of months. Tea Party fractured the party, Trump took a sledge hammer to it.
He's not going to go off the handlebars, he's not going to institute a fascist government, dude is pandering so hard that it's stunning that the entire world hasn't caught on.
Besides, this is all going to come to ahead at the RNC with a brokered convention where he is going to have the nomination stolen from him. If that doesn't happen then GOP will run a third party candidate to try and cut him off from the party.
There are too many checks and balances to have a president basically destroy a country on his own. Nobody would authorize a nuclear strike because he wanted to, that's now how the system works.
And on top of that there is going to be a huge opposition when it comes to the general.
