All of the flipped states stopped counting at once. This is not a normal thing
The betting odds for Trump jumped a bunch, which is the cause imo.

Seen this tie before weeks of markets turmoil over the uncertainty, scalpers dream![]()
Yep. Bush/Gore in 2000. Back and forth for weeks and weeks. Florida's "hanging chads," etc, etc... Trading fun!
Odds from my UK bookmaker have been around 1.5:1 for Biden and 2.5:1 for Trump for several weeks. Suddenly they have reversed and widened - 1.44:1 for Trump, 2.75:1 for Biden.
(as I type this, Biden has 220 EC votes, Trump 213)
%%Overnight, your wife just called, she said you could put your guns away, wash your face, and take bullet-proof vest off, and go to bed. Trump is gonna win!
