she started with a promise to do price caps or some such, that combined with the campaign calling the republiklans weird was doing numbers on the polls. So of course they dropped all those and started going around with Liz Cheney while refusing to drop Joe Biden and his genocidal legacy.

so yeah, either you're correct or they're just really bad at this

I don't think it was their choice to run her. The choice they made was to nominate Biden's corpse to prevent the contest for the next Democratic nominee from becoming a referendum on genocide. She was the backup plan after that exploded in their face.
