I do agree that we can’t totally trust in DT being Conservative, he could be a decoy, a liberal. But I don’t know if he is that either.
Trump has a long history of being a liberal. As recently as 2013 he praised former NY mayor Michael Bloomberg for "putting his money where his mouth is on guns". I know of no conservative who believes that Michael Bloomberg's efforts in trying to take guns from law-abiding citizens to be a good thing. Not a one.
Donald Trump is a liberal and he cannot be trusted.
