you have zero idea what other conservative people watch or not watch college or professional football. you can ONLY speak for your own self
While the breakdown is slightly skewed to the left compared to the general voting population, it is evident that many conservatives follow NFL football. The Norman Lear Center, which of course is liberal, posted a study in 2017 that stated that the following NFL teams had the most conservative fan bases:
Tennessee Titans – 37%
Kansas City Chiefs – 35%
New England Patriots – 35%
Denver Broncos – 34%
Jacksonville Jaguars – 34%
Considering that the area where the Patriots and Broncos play are liberal Democratic leaning, it is further evidence of conservatives following football. (The study was done in 2016, so there may have been shifts since that time.)
