I did not support Biden during the primary because I thought then as I do now that he was too old in addition I was disappointed in him when he gave up his turn to to Hillary, and consequently gave us trump.
I blame trump on Hillary, Biden and Obama. trump did not win as much as Hillary lost.
I am sure when Obama sought the support of the Clintons after he won the nomination, and a deal was made that offered the office of Secreter of State, to pad up her CV, and another shot of the presidency after his term to Hillary.
So IMO trump was in part a product of Biden and Obama.
Oh what a tangled web we weave....
Because of the above and many other reasons I supported Andrew Yang. His Universal basic income idea , given the disruption that AI technology is already bringing but will escalate in the coming decade is inevitable if we hope to survive as a federation. And Young is smart, very smart , if he had won the nomination it is my opinion that he would had pivoted more to the center and had been a strong candidate against trump.
But I am a pragmatist and supported Biden in the General election.
as to my opinion, I believe I am allowed one as much as anyone else, I don't think my opinions during the primary disqualifies me from having one now. My judgment is debatable.
But what is not debatable is that Biden is too old.
