Democrats have a huge advantage in coming elections given how much of an unmitigated shitshow Trump 2.0 has been, but the party itself still doesn't know what time it is and has very little of substance to say on anything (except the younger DSA wing). The field of Democratic candidates is also pretty abysmal. AOC is seen as radical and unlikable outside the left (unlike Bernie who was seen as radical but likable) and doesn't have the same excitement around her that she used to even among progressives. Bernie and Warren are too old. Kamala Harris would be a disaster for obvious reasons. Gavin Newsom is overtly corrupt and insincere.

It seems to me very plausible that Democrats could still fumble the bag in 2028, especially if Kamala takes the nomination or if some other black swan event happens (Trump dies in office, JD takes over and runs a relatively competent administration; or Trump and JD become horribly disgraced even among MAGA, leading to Tucker Carlson running—in which case I think he'd win handedly against a generic establishment Democrat).

There's also the problem of the main Democratic contenders simply being not very good. A Democrat in office would be miles better than a Republican, but I'm not at all convinced that a generic Democrat would be prepared to face the enormous challenges we as a country face (soaring debt, money in politics, AI, eugenics/transhumanism, Israel/Russia/coping with multipolarity, a highly fractious cultural and political environment, a public that finds classical fascism/white nationalism increasingly enticing).

The only person I can think of that is both electable and suited for the current moment is Jon Stewart. He's a political moderate who's comfortable calling out the establishment. He's well read. He's broadly liked and respected, even among people who disagree with him. He has a highly dialectical style to politics (ie. bringing people together to hash things out), which I think is sorely needed right now.
