We lost because the incumbent president had a 39% approval rating and 70% of Americans felt we were on the wrong track.

71. Pretty complicated to say an incumbent President shouldn't seek reelection

As far as Biden digging holes in the House and Senate. Biden's polling numbers weren't any worse than any other Democratic candidate other then fantasy candidates like Michelle Obama until a flood of big Democratic donors demanded he step down and some of those same polls were funded by Democratic donors that had an agenda to get him to withdraw from the race.

Biden does have some blame in this, but so does the entire Democratic apparatus from the big donors to the Congress to the Senate etc. Maybe Biden could've recovered if Democrats would've been willing to rally around their President. We don't know. Maybe he falls on his face in another debate an losses. We don't know, but what we do know is what actually happened. The people who called for Biden to step down got their way with an alternative candidate and not only did we not win the Presidency, but failed to take back the House and lost the Senate too.
