So I've been reporting a story about how you'd fix the impeachment process. It doesn't work for removal, as currently designed. Impeachment was built for a political system without parties. It fails in a system with polarized parties.

The one time it functioned as intended, confusingly, was the time it didn't happen: Richard Nixon wasn't impeached! But the impeachment process, which came at the low ebb of party polarization in American history, convinced his party to force him to resign.

Would Republicans force Nixon to resign today?

Oh, you're cute. Thank you. I needed that.

The problem of impeachment is pretty simple: Presidents are leaders of parties. Parties are tied to the political fortunes of presidents. You're asking a party to basically wreck its immediate political future for the good of the system.

This doesn't just have the effect of making impeachment ineffective as a remedy. It's worse than that. It makes impeachment dangerous to the president's party, and gives them a reason to defend him and either normalize or minimize his crimes. As we are seeing right now.
