Krugman makes the point I've been making for months: focus on the corruption.
Yes, Americans hold a dim view of the morality of their elected officials - the alleged crimes of Swallwell and Gonzalez add to this perception (though it's worth noting that Swallwell went from allegation to suspending his campaign to resigning from Congress in about 72 hours). However, they also really don't like corruption, and corruption IS the point of authoritarianism. It is the lack of accountability to the public that motivates autocrats to retain power.
Trump is a shitty businessman, but a shrewd manipulator of graft. He didn't want to cede power on January 6th because of his colossal narcissism, but also because it was easier to make money off being in power. Right now, there are clearly large sums being made around insider trading on prediction "markets" and outright graft through his crypto. If he were to lose power, he would be vulnerable to prosecution.
The results in Hungary are a positive development in the war against international illiberalism. We should keep an eye on how Magyar prosecutes Orban's crimes, too. What we DO know is that corruption played a massive role in motivating the Hungarian people to vote in such numbers that Orban couldn't steal the election.
Similarly, Democrats can leverage people's outrage over things as mundane as the tearing down the East Wing, to as sordid as Epstein, to as lethal as his war in Iran to paint Trump as a corrupt oligarch out to make your tank of gas unaffordable, while coddling his friends in Saudi Arabia.
Corruption is the rug that really ties the room together, man.
