There's basically no difference between 51% GOP odds and 49% GOP odds, so it's gonna be funny to see people react hysterically to this, and then again when it switches back to 52% Dem in three days, back to 51% GOP in five days, and stuck at 50% the day of the Election.
This. People assume a level of precision where none exist, it seems. The same thing happens, relatedly, with polling averages. When a candidate is up by 1-2% (polling biases of late notwithstanding), people assume that candidate is going to win and it would be a major upset if they lost, when in reality being up 1-2%, even in the aggregate, means nothing and is essentially the same as the race being tied.
