It's a bit reductionist to boil Obama down to the shit implementation of Obamacare that the GOP killed in the womb. I encourage you to read on it. TL;DR, it was gonna be pretty good, but the GOP threw a fit that it was going to be a win for Dems and tanked it. You're also leaving out the fact that Obama expanded gay rights and got talking about climate change on a policy level. Should both of those things happened sooner? Yes, but that's letting perfect be the enemy of good.

Biden isn't amazing and honestly, I don't care for him much. However, I doubt he letting the genocide in Gaza happen for profits. With the Dem's own party, Israel is a divisive issue and I'm sure he's having to tread carefully so it doesn't shoot in the foot later because politicians are scummy petty people
