Florida, Florida, Florida!
Florida, the ultimate swing state, has played a decisive role in too many presidential elections. Every single vote counts in any statewide election there. In 2018, Republican Ron DeSantis beat Democrat Andrew Gillum 49.6% to 49.2% in the gubernatorial race and Rick Scott beat Bill Nelson (basically a walking corpse) 50.1% to 49.9% in the Senate election. Two years earlier, Trump had beaten Hillary 49.0% to 47.8%.
