The president sets the tone of the administration. Ultimately they are the big boss, but they don’t do everything.
I take issue with being called a Biden supporter. Biden is mediocre at best. I’dve much preferred if a more…motivational, I guess, DNC candidate in 2020. We obviously knew that whoever won would be 4 years older (and many more battle-worn) come re-election, and it’s pretty unorthodox for any party to let the incumbents president be primaried. I can’t think of a time.
In fact, I think the DNC was secretly hoping that Biden would’ve bit the dust 2 or 3 years in.
