political divides of sports team fans

[Rockefeller GOP]

The Cubs Republican/White Sox Democrat idea has been held so misguided that studies have actually been done to disprove it.

I don't really know where the idea comes from anyway now that we have moved out of the 1980s.

Minority south side wards are 90+% Democrat, yes, but white north side wards are 70+% Democrat. Meanwhile, southern and southwestern suburbs (with the exception of the closest ring, as is the case throughout the closest ring) are decidedly more conservative than their counterparts. North and northwest suburbs are mixed and lean left.

That article you linked literally said that the Cubs fan base is more Republican, and that only included Chicago area residents ... Once you include the rest of the state, it's pretty clear the Cubs would have a less Democratic fan base.

If you're including college football teams, I can say that the UW vs. WSU divide can definitely have some political overtones. Ask a diehard UW fan to describe a typical WSU supporter, and they'll give you a bunch of Republican/Tea Party stereotypes (country hick, uneducated, redneck). Ask as diehard WSU fan to describe a typical UW supporter, and you'll get a bunch of stereotypes of Democrats (elitist, snob, pothead, etc.)

Funny how the stereotypes of what types of people are Republicans and what types of people are Democrats vary a ton by where you live apparently.  Especially funny, because wasn't there an article showing that Tea Partiers are actually better educated and have higher incomes than the general population?
