Genuine question to Democrats: why so loyal to Biden?

[LabourJersey]

I'm loyal to the Democratic party and not necessarily Biden.

I have to admit that a lot of Biden's legislative accomplishments in the first 2 years, while impressive, are more the result of a more ideologically cohesive Democratic party.

Biden was admittedly not my first choice for President in the '20 primaries (or my second, third or fourth), but he was the nominee. And American presidents are uniquely insulated from political party pressure nowadays - there's a reason why only 1 modern president has ever resigned, and only one stepped down when he could run again (Truman, and that was an odd case).

I did think that there was benefit to incumbency, but at this point I'm not sure. In retrospect the benefit of incumbency that Obama, Bush and Clinton clearly had in their re-elections came from their ability to direct the narratives. Biden, partially because of his personality, partially because of his age, partially because of the media, cannot do this.
