Genuine question to Democrats: why so loyal to Biden?

Because he's the sitting Democratic president and a good person who has done a lot of good things.

Could even say he's the new father of our country.

Lack of options thanks to the DNC.

I liked Biden as VP, but his administration has been way too far to the left for me. Not the far left in the traditional Marxian sense (that would actually be preferable) but they've pandered way too much to the cringe Twitter / academic left.

I'd have preferred virtually any younger more centrist Dem, or even Bernie. At least Bernie is an actual social Democrat, not a center right Dem pandering to the academic wing.
