I'll take Biden's delegated style of governance any day which is why I voted for him. It was a vote for competence.
I scoff at the idea Biden would "do and say what he's is told to do and say," Joe Biden? All sane presidents will be guided by expert advisors but they still do get to make the decisions and suffer the political consequences of any calls that may reflect personal preference more than consensus of their party from time to time.
As far as Trump doing what he wanted when he wanted, that was not actually his constitutional brief, which the congress and courts were ready to remind him from time to time. Not that he learned anything from what they said because he only cares about himself 24/7/365.
Joe Biden has worked with administrations and legislators for decades, and across the aisle at that. If he appears to be doing what "someone else" suggests, it's probably because a majority of Americans are actually that someone else. Both his Congressional floor leaders are skilled vote counters and I can't vouch for Mr. FlipFlop K McCarthy but McConnell's certainly no slouch at that either. Biden is extricating America from a 20-year war. You think he can do that all by himself or would take advice from just one person on that?
