I have zero against Trump on a personal level -- if he was a neighbor, I'd be delighted if he would come over and visit for a cookout.
I'd tell him about Christ, probably, as it's very evident he barely knows anything at all of the religion he wants to merely use as a banner, for cynical political manipulation.
I totally object very strongly to Trump being president -- he is very badly suited for the job, and causing a lot of harm.
Ironically, the group among the evangelicals that voted for him are said to hope he will preserve and protect their way of life -- the sharp irony is that Trump will powerfully endanger that very way of life for them they hoped he'd preserve.
But, for any real believer, the only true hope and security is Christ, and never any mortal man/leader here on earth.
