right wing fans? I would guess the PAC-10 has the most liberal sports fans. The Big 12 (especially without Colorado) probably has the most conservative. The SEC is a close second. The SEC has more african american fans to offset the total while the Big 12 is mostly in white areas.
SEC would be my guess for right wing fans since it's in the South, with the Big 12 close second with most of the schools in right-wing states. I would agree with you that Pac-10 has the most left-learning fans of any college sports conference.
