Exactly.
I didn't expect Lindsey Graham to lose (the polls had him marginally ahead) but to see Susan Collins ahead is a shock. Perdue had a disastrous debate and still somehow won.
In the Presidential race, the only polls that looked accurate in the battlegrounds were the Seltzer poll in Iowa and Rasmussen and Trafalgar in Florida. Even accounting for the early votes, that fact that Biden has to fall back on the blue wall (which is by no means guaranteed at this point) means the polls were totally off.
