For a house seat, two years of harm can be better than being stuck with them as the representative of the Democratic Party indefinitely due to the rarity of successful primary challenges to incumbents.

Are two years of harm right now better? I dunno, it’s certainly a fraught time, but it’s also unlikely an individual seat is going to be the tipping point. And these centrists are particularly unreliable defenders of liberal democracy should they end up in that position.
