California: USC, UCLA, Stanford, Cal
Texas: UT, TAMU, Baylor, TCU, UH, TTECH, SMU
Florida: UF, Miami, FSU, UCF
New York: SU
The division of fans amongst the P5 teams in the largest states clearly favors SU. It should not be a surprise that SU would rank relatively high with this type of built in advantage, especially with three historically successful and significant programs.
Alabama: Bama, Auburn
South Carolina: USC, Clemson
Georgia: UGA, GATech
Ohio: tOSU
Michigan: UM, MState
Pennsylvania: PSU, Pitt
North Carolina: UNC, NCState, Duke, Wake Forest
Checking in on other P5 states, only Ohio has a large population and one P5 school, thus tOSU's large following is easily explained while UM's is somewhat split, as is Pennsylvania's larger population. Alabama with a small population is split, likewise South Carolina is split other states are not significantly populous and likely have multiple teams.
Overall, the analysis makes sense.
