You make a valid point, but the reason people are undecided is that they they have no properly informed opinions. I hate this narrative that Biden is ineffective. Biden has done a lot of good things. And where congress failed, he found a way to get shit done anyway. People don’t know that because media sucks and their echo chambers don’t tell them. Or alternatively, their expectation about what a president can do in one term is completely unreasonable.

And that is all while ignoring that a republican congress will hold back the entire country for years just to make sure their guy looks better. And it works! People complain about shit not getting done but couldn’t tell you how their representatives voted on those things.

So yeah, pretty much what you said. They think the candidates are roughly the same, but they have no clue how what their candidates do actually affects them.
