Yup a tie is highly unlikely, but there’s several bits of interesting information in this video.
That video also states that Texas, California, New York, Florida, Illinois, Pennsylvania, Ohio, Michigan, Georgia, and North Carolina contains more than half the U.S. population.
Rock, Paper, Scissors?
I have actually heard that in the case of Florida (and remember how close 2000 was), they flip a coin! I have not fact-checked this yet, but that would make for some interesting tv.
