@freemo @LouisIngenthron presidential races aren't all that matters, and you'd need a race that was close enough electorally that a single state flipping would flip the electoral college AND where any of the states with enough electoral votes were very close.
I can give you one example you should be well aware of with a *very* slim margin (that ended up not mattering because of other highly questionable decisions). Want to take a guess first?
