I've been seeing Trump/Alexandria Ocasio-Cortez comparisons, but beyond their both having social media acumen and appealing mostly to the non-centrists in their parties, I don't see the similarities.
I think we're only beginning to see the different ways that the new media landscape allows for popular figures to emerge, brand themselves, and communicate with the public. The way they each engage on twitter is very different: Trump almost never directly engages other users and doesn't participate in memes or show awareness of online culture. AOC is spectacular at that...
Obviously part of my defense of her is that I agree with her politics (for the most part... i always think progressives are maddening in their inability to grasp the way regulations and red tape can restrict freedom). And she's certainly a partisan and a sharp critic of elites, not a centrist like Clinton or Obama.
But I think a real liberal version of Trump is more like Michael Avenetti. Trump just completely lied about his actual positions and intentions to get elected and get laws passed (planned parenthood, health care, the impact of his tax cut, preexisting conditions, lgbtq rights, etc.). AOC seems to be actually telling the truth about what she want to do.
