Who's won the most college football national championships?

"The advent of the College Football Playoff at long last gives some uniformity to the awarding of national championships. With the exception of the 2003, the Bowl Championship Series mostly resolved the problem of the AP and Coaches polls recognizing different national champions, which had been a problem ever since the two poll began existing alongside each other in 1950. 
Prior to the introduction of the AP Poll in 1931, the world of claimed and unclaimed national championships was like the Wild West. For that reason, championships from 1935 and earlier have been excluded. If we were just going by claimed national championships, though, Princeton (28) and Yale (27) would be the runaway leaders.
