He's in a much stronger position than he looks like. The Democrats so relentlessly hammering him and catastrophizing everything he does means that if things don't actually turn out all that bad (if the economy stays strong and no wars break out), they'll look rather silly.
I agree with this analysis. I think that "The Resistance" concept is way over the top and will become tiresome over time. If the country starts going to Hell in a handbasket, there will be independent voters who will blame the Democrats' shrill opposition and vote for Trump.
I also believe that Trump understands politics as few do. And he's been proven right in his political instincts every time folks say he's stupid, off his rocker, going to blow it, etc. Trump's not as stupid as Democrats think he is, ahd they'll pay for that miscalculation if they don't adjust their game plan.
This. Big guy, small shadow.
