It’s been a delight watching them flail uselessly. They knew they might have Harris as an opponent from the instant someone as old as Biden selected her for VP. They’ve had all this time to do oppo research and focus group what is likely to stick.
All their arguments against Biden evaporated into nothingness the instant he bowed out and they are completely unprepared to run against Harris.
They counted on Biden being a stubborn idiot and staying in the race and didn’t have a backup plan.
