The reason I believe Trump is dangerous is that, after he lost an election, he started making constant public demands for the results to be nullified, interspersed with occasional declarations that he had definitively won the election and intended to remain in power. I agree that many prior criticisms of him were speculative or untrue, but it seems clear that he was prepared to install himself for a second term by any means available.
