In 1919, horse race betting was banned in every state. How times have changes. Horse betting is now legal in 41 states.
If you’re wondering, what are the places where it still remains illegal? Interestingly, it doesn’t appear to fall along partisan lines, with a curious mix of red states, blue states, and swing states still outlawing the practice: Alaska, Georgia, Hawaii, Mississippi, Nevada, North Carolina, South Carolina, Texas, Utah, Washington D.C.
(In 1919, Kentucky and Maryland were the only two states which allowed an adjacent form of horse race betting called pari-mutuel, in which people bet against each other rather than against the race track.)
