I know that there's no real way to find out, but I want to see what people think. What percentage of different sports fans vote for the Republican\ Democrat in an even election?
My Predictions:
Football fans: Republican 55, Democrat 45
Basketball: Democrat 75, Republican 25
Baseball: 50-50
Hockey: Democrat 85, Republican 15
NASCAR Racing: Republican 90, Democrat 10
Golf: Republican 85, Democrat 15
Tennis: Not sure, but I'm guessing Democrat?
I can only comment on hockey as you can tell.
One thing is probably for certain in football and basketball. Pro fans are definitely more Democratic while college fans are definitely more Republican. I would think Pro football has a narrow Dem lean, while basketball has a strong Dem lean due to it's urban nature. College football and basketball fans are definitely strong Republican outside of the West, Midwest, and Northeast/Mid-Atlantic and probably tossup/lean GOP in those regions.
Baseball is almost impossible to call.
