For Democrats to survive the 2022 midterm with their majorities intact they must walk a very, very narrow tightrope. They also need a number of things that are mostly out of their control to fall into place. One of those things is the hope that you will see some replay of what happened in 2010 and 2012. The first was an extremely good year for Republicans. The second was just so-so — Mitt Romney lost to Barack Obama after all. But it should have been a decent year for Senate Republicans since Democrats were defending their class of 2006, when they’d won Senate seats basically everywhere. In both years Republicans failed to win the Senate even though by rights they really should have. They just kept nominating crankish and extreme candidates in races that should have been winnable. That’s why there’s a Senator Chris Coons (“I’m not a witch”). That’s why Claire McCaskill (“Legitimate rape”) had one more term in the Senate. There are a bunch of other examples.
