Centrists lost to Trump, the objectively worst candidate for president.

Sanders received a loud applause from a Fox News town hall. I'm not so sure he'd have lost.

When voters have chosen the option furthest to the right it is stupid to think that running a candidate further left would do anything but lose.

Trying to do right-wing policy "better" than the right-wing candidate has consistently lost elections to far-right candidates. All it does is validate the far-right candidate's positions, and they'll always be considered "stronger" on those positions

People primarily vote for change, and that's exactly what the centrists haven't been able to offer. It's why Biden lost, it's why Harris lost, it's why Clinton lost.
