How do fraternities and sororities members vote?

Greek life people, at least fraternities, tend to be douchebags. At my undergrad during the 2016 election one of the houses had three dudes sitting outside with a "honk 4 Trump" sign.

Fraternities (at least the heavily white ones) strike me as very Bro-ey organizations with many Trump supporting Evangelical/Conservative-Catholic former high school athlete college students.

Sororities and more diverse fraternities strike me as having members who are heavily establishment Dem.

I knew plenty of "quiet, bookish" girls who were in sororities but that type of guy is basically absent from Greek life.

Quietness and Bookishness isn't really a thing among American men though, to be fair. Most guys in the United States conduct themselves pretty extroverted and gregariously.
