What do you mean in this context by "deal with it"
Is it to shut up for four years? Because the benefit of having a POTUS, rather than say a king or a dictator, is that you can acknowledge that he is rightfully POTUS whilst complaining about the myriad ethical, procedural and policy differences you have with him.
Or is it "deal with it" in trying to get him to not serve the full term by getting impeached or to resign? Because on the evidence of the last few months Trump seems to be conspiring in that goal!
