Historically, presidents take credit and the blame for things they didn't do. Economic policy is one example. They actual economic changes take time to really be felt on main street. Very often those changes occur just before they take office or after they leave.
And despite presidential elections being the SB and WS all tied into one competition, the real path to controlling the government is through the house and senate. But THOSE elections aren't as cool.
I never said I attributed anything 'good or bad' to Biden or even Trump in my statement. I said presidents take credit or blame by the public for things that were beyond their control.
