Trump is sui generis, not analogous to what used to be the Republican party.
He's not confined by such bullshit, though he will dish it out if required.
I don't know whether I can trust Trump or not, all I know is he hasn't yet joined all the other politicians stabbing me and my family me in the back.
Yet.
The Republican party was defined to long by the elite that pushed free trade neocon wars while keeping the base distracted over social issues they did nothing about when in power (abortion has been legal longer than I have been alive and I am middle aged - but pretending to want to ban it raises lots of money). Good riddance to that Republican party.
