i’m not necessarily saying they’re trying to lose, but i don’t think they really have any principles or agendas that drive them to actually desire the levers of power

The way I describe it is that Democrats do want to win, but they only want to win if it's on their terms. This explains why they kneecapped the most popular politician in the country running on an incredibly popular policy, but also accounts for the fact that the careerist lanyard caste would prefer jobs in a Biden administration to having to scrounge up other work for the next four years.

It also explains -- especially that second part -- why Democrats can't just tank the Senate if a leftist candidate wins the presidential nomination. The wheels on many Senate campaigns are already in motion by that point, and all the people working on those campaigns (as centrist as they may be) want to win.
