It's a bit hyperbolic in this context, yet also technically accurate in a surprising number of ways, though mostly I was focusing on how he won't allow an election to determine who gets to be the Democratic nominee. Also, he has the legal ability to murder his opponents, and is both supporting (in Gaza) even while also decrying (in Ukraine) genocide. Anyway, the point is that he is suppressing opposition (from within his own party, by not allowing a debate about who may replace him), which yes he has the legal ability to do, fwiw. So he is not much of one perhaps, but has some characteristics not entirely dissimilar to one.
