67% of Democrats want someone other than Biden; 82% can’t name who they want

Americans aren't happy about something but can't name an alternative. News at 11. Also, water is wet.

So many candidates would be better than Biden. Evers, Shapiro, Mark Kelly, etc.

I feel like the universal expectation in the 2020 primary was Biden was going to defeat Trump and serve one term after. The one term and pass to the torch expectation kind of smoothed over age concerns in the primary. Most Dem voters were probably not expecting the idea of voting for a soon to be 86 y/o President down the road. So the polling on this makes sense to me. Biden has accomplished enough that he could step aside and still have a respectable legacy but there's his ego and he boxed himself with Harris, maybe on purpose.

There was also something of an expectation that if Trump lost he’d retire from politics, due to reports he didn’t like the actual job of the presidency during his first term.

If Trump didn't run again, would Biden ?

Yes. Biden is a selfish person who puts his personal interest above everything else. See the depletion of the strategic petroleum reserve for political gain.
