Polls are crap
It’s a little bit notable how they change over time, but mostly it is just a bunch of poor methodology noise
But, I do feel it’s relevant to point out that even in polling land Biden has been gaining for the last few weeks and it’s notable which media outlets are pretending it is the opposite of that (like severely the opposite) and to wonder why that is
Honestly, casinos have a reason to try to get it right. When pollsters get it wrong nothing really happens. I more or less agree with the logic of just looking at the casino odds as as much of a thing to trust as anything else.
Also, it’s apparently illegal to bet on the presidential election in the US, which I didn’t know.
Or… Not a good idea to allow bets on stuff the people betting can influence
