re: Is there a single Democrat here who will post their support for Biden’s presidency so far?

I like his stimulus bill + infrastructure bill.

I like the policies he's proposed on his website including increasing capital gains taxes for the highest earners.

There are things I don't like about Biden as well but there are plenty of things I like about his presidency. It's intellectually dishonest to keep parroting that nobody can't bring anything up that they like about Biden without mentioning Trump. Multiple people have pointed out things they like about Biden.
