Most US Presidents were in fact members of college fraternities. Remember, the origin of American college fraternities goes back to 1776. Most of those men attended a handful of colleges in the northeast, which were incubators of the early social fraternities. Fraternities remained in orce at Ivy league schools until the 1960s. Even today, fraternities are coming back at Harvard, and DKE remains at Yale.
Regarding Bill Clinton and Kappa Sigma, it would not surprise me if he was some sort of social affiliate at Arkansas when he attended law school there. That is one of their strongest chapters - maybe their best in he country. Clinton would have enjoyed the parties.
