You can do both.
I like reading the World Socialist Website (which is basically so leftist that it's against anyone even slightest bit left to it, treating Jacobin the same way it treats the Democrat party). They point out that Jacobin has published articles attacking the Lockdown, and also saying that the Gretchen Whitmer plot was some exaggeration.

The Jacobin ought to be treated carefully. Not that I am saying that what it does is wrong or invalid of course.
I think the stuff in the Jacobin article that isn't talked about is Biden challenging Reagan on apartheid, and other progressive stuff he did. His work overseeing Obama's stimulus which helped out of the Great Recession and directed funds to Green Energy. The bad stuff ought to be balanced with the good. As for criticisms about the ACA and so on...that's valid but it can't be denied that the ACA we got still helped a great many people in America and black and brown communities in particular. Maybe Obama was too timid and comfortable with neoliberal oligarchs and so on, but a lot of right wing seem to hate it.
Here's something y'all need to understand. Obama was so hated that the right-wing turned to a supervillain like Donald Trump, but no supervillain will come for Bernie Sanders, or for that matter AOC. At least not yet.
Robert Caro said of Lyndon B. Johnson, "There's an old saying: 'All power corrupts, and absolute power corrupts absolutely.' The more I've learned, the less I believe it. Power doesn't always corrupt. What power always does is reveal. When a guy gets into a position where he doesn't have to worry anymore, then you see what he wanted to do all along."
Ultimately we will know what Biden is and what kind of person he is in the next four years, just as we learned who Obama was in his 8 years. Obama was the one behind drone bombings but also killed Bin Laden, Obama was the one who ran anti-immigration policies, but he also did the Cuban Thaw and passed the Iran Nuclear Deal. Obama refused to send ground troops in Syria and drag America into another Iraq when shove came to push.
