I never suggested Biden turn his back on anyone.
I believe we were discussing the formation of a third party.
But since we're on the subject now, I will say this.... it shouldn't be put on Biden's shoulders to either totally, 100% satisfy any one faction of his party, nor put him in the position where he might be forced to... or be seen as.... or be accused of.... "turning his back" on anyone.
Leading the nation has never been a one-sided, winner-take-all proposition.
Everybody has to give and take a little and be happy with a leader who is trying to do what's best for us all, rather than expecting him to pander to one's own set of desires and demands and give one group everything they want against the wishes of all others.
That is selfish and selfishness is at the heart of what's wrong with us as a society.
