Congress has effectively become a three-party system, with the Hastert Rule being abandoned for most enacted legislation in the last few years. The Vichy Republicans may as well make this more explicit by forming a minority government with Democratic supply votes, perhaps giving a few members of Pelosi's clan strategic chairmanships. Then perhaps voters may wise up and primary them, and judge the effectiveness of the Congress as a de facto coalition government rather than a Republican majority.
Interesting idea.
Of these choices, probably Xavier Bercerra. I think Pelosi is an objectively good Speaker, but wasn't great at selling the Democratic Party to the voters, and I blame her in large part for how bad 2010 ended up. I think Bercerra would probably be better at least in that regard.
