For example, they had to have known that McConnell would kill the Trump impeachment. But they went ahead with it anyway. The only explanation I can see for this is that they wanted to somehow signal their opposition to Trump with their core voter base, while wasting and effectively discrediting the usefulness of a last-resort tool for asserting their authority.
And what is Biden campaigning on? What is his campaign even doing [0]? Where are the attack ads branding Trump as an anti-American grifter? This feels like 2016 all over again, except with the added danger that we already know how dangerous Trump is, and if he wins again he'll have nothing to lose -- and his handlers in the halls of power will take full advantage of it. They know they are ruining America and they simply don't care, they'll just run to the bunker when shit gets bad for normal people [1].

w.r.t Sanders: he lost in a small d democratic primary. It wasn't the leadership: it was the voters that chose Biden over Sanders.
You think they don't understand this stuff? Democrats have been deliberately "failing" to get shit done for 20 years. They keep holding out progressive and populist policies, tantalizingly close to enacting meaningful change -- but nope, somehow it always seems to be a matter of political strategy, badly run campaigns, and bad messaging that derails things.
Surely the Republicans haven't somehow had the better political strategists for decades. They aren't always better funded and they aren't always better organized. And certainly they don't have access to some kind of magic politics potion that the Democrats lack.
The only plausible scenario that I can see is that the Democratic party leadership has no interest in actually getting policy enacted, as long as they keep their cozy niche in power. Another 4 years of Trump will help them do very well in the 2022 midterms, and it will help keep their friends at the NYT, CNN, and MSNBC in business.
It would also explain why they hated Sanders and the DSA candidates so much. Liberals (not to mention leftists) who actually wanted to take power at the national level and actually do something? That would fuck up the whole game.
Basically you'd have to show me some actual evidence that Democratic party leadership actually wants to do anything other than campaign on a progressive platform and consistently almost-win. The whole thing seems worked to me.
