This might be fun to see how our fan base is politically. Cast your vote, or how you're going to vote here...
Other. I can not and will not vote for either of the two major candidates. I don't know who I'll vote for yet, though. Libertarians are too far gone, and there's no McMillin on the ballot this year. I am seriously considering null voting the President and focus down ballot.
I most likely won’t vote in the presidential. More concerned with my local races/senators and congressmen
I’d start with equating “fan base” with “alumni base” because I’m not sure how else you bound it. And then I’d look at those demographics. Looking at the 2018 demographic splits, white college educated women went 59 D - 39 R. That’s the largest demographic in our alumni base. White college educated men went 47 D - 51 R (our second largest demographic). All nonwhite voters voted in favor of Ds over Rs. Due to enrollment growth, our alumni base skews younger than the population on average. And more and more students over time are coming from more moderate/liberal areas of the country (CA, CO, and urban areas). National demographics would certainly project out to a Lean D, but I presume rural voters and white evangelicals are also over-represented relative to national totals in our alumni base (especially so in the population born before 1980). All taken together, I’d guess it probably balances out pretty evenly—but with a definite trend line over the past 20 years from right to center/center-left. Certainly nowhere close to the 80/20 split in favor of Rs on this board.
I see where you're going with this in terms of being able to quantify, but surely we have to realize that the segment of TCU alumni that follows sports is a relatively small portion of our alumni base.
