Pete would be a kind of Obama. But remember that Obama created the conditions for Trump. Honestly, people like them are worse because they get people's hopes up and then crush them with their (in)actions.
The only way to escape the cycle of neoliberalism (sham democracy, fascism, sham democracy, fascism, etc.) is to elect someone who is not a neoliberal. Someone who has a socialist mindset and can put democracy above capital. Someone who can acknowledge and attempt to fix real systemic issues which keep people down. Someone who is willing to tackle wealth inequality head-on through unapologetic redistribution. And maybe this should be first: someone who actually cares about workers' rights and wants to make it so that all the technological advancement benefits them too, through shorter workweeks and shorter workdays. We need a kind of person similar to people in the past generation who never stopped until they got the weekend and 8h workweek, that kind of character, someone who dreams big and fights for like a 3-day workweek of 4 hours each, and mandatory shares for each employee same as minimum wage, which btw should be like triple what it is now. And someone who believes that billionaires should not exist, i.e. can tax them to sub-billion wealth. (I know, craaazy.)
And of course to actually apply the law and prosecute the fascists and their propaganda machine (media, think tanks, billionaire donors) the way it always should have from the beginning since they've been conspiring and committing treason for decades. Sedition I think is the word. (And if this sounds like an exaggeration in the style of MAGA pundits, that's because every accusation is a confession with them. They preemptively accuse their enemy of doing the same thing they're doing so that it sounds crazy or at least unoriginal when they get accused of it later.)
Without very bold changes like the above, we are doomed. Mayor Pete cannot do that. He's a neoliberal with maybe one good idea, like abolishing the Electoral College or something. But it's not enough. The US needs Reconstruction.
