They will stick with the "(D)" no matter what. I do bet a lot of them wish they had coalesced around Klobichar or some other D candidate. 1/3 of this country will ALWAYS vote for and provide cover for "D". 1/3 of this country will ALWAYS vote for and provide cover for "R". There is about 1/3 in the middle that shows any willingness to be persuaded or to logic out individual arguments/issues.It would be interesting to learn why Anyone who voted for Biden because they thought him better still thinks Biden is better.
What possible reason could ignore the reality ?
They may not say he is better than the other D choices now, but they will always stick to the party line and say he is better than an R. That's just the way 2 party systems end up working. Unfortunately.
