Not remotely. Trump is quite different and does have some qualities that suggest he is a Dictator. May is just between a rock and a hard place. Yes she wanted us to Remain but having picked up where Cameron left off (ran from), she has had to plough a very difficult path between the EU leaders on the one hand, and they were never going to make it easy for the UK to Leave, and our Parliament, which is full of individuals after their own agenda. If ever there was a time to pull together, it should have been RIGHT NOW. Unfortunately it's far from the way things are working out.
I'm not sure how she's kept going, to be honest.
