Look, Bernie don’t like Pelosi for her poor track record, under her leadership, the Democrats had lost more seats despite being in the height of Obama’s first term and failed to maintain control of both houses. That’s why most Bernie supporters (and progressives for that matter) don’t like Pelosi, her leadership isn’t great, that and her own neoliberal policies also irritates them to no end
by the way, I, including most other Bernie supporters do voice our disagreements with Bernie on alot of policy positions he supported, largely foreign policy but the concept still applies, we’re not a bunch of Bernie cultists who blindly support him no matter what, we are not like Trump’s cult of personality whatsoever, we just saw how often people from more establishment positions of politics tend to have less then wholesome reasons for their views.
Also, I (and again, most Bernie supporters) are all for resisting trump but we like it if it was more effective resistance, by which we mean resisting Trump via opposing his policies and calling him out on his most monstrous policies, like continue support of Saudi Arabia and their war with Yemen, or his own blatant annulment violations, and so far, Pelosi, and other centrist Democrats, seem to only resist him via his behavior, which we’ve tried that back in 2016 and that evidently didn’t work, so why haven’t she and the rest of the neoliberal branch of the party change their approach in their resistance to Trump. But generally speaking, Bernie supporters/Progressive Democrats simply disagree with them on the approach to resisting Trump, of course, I didn’t expect Trump to be removed from office anyhow, the Republicans control the Senate and the likelihood of that happening is rather nonexistent, at least in what he was impeached for, because again, there was a more likelihood of him being removed from office (not much but still) if it was on something like annulment violations or some other equally blatant violations of the constitution.
