Withdraw your children from GWU. Refuse to support idiocy and lunacy.
The student senate does not set policy for the GW. In many elections the percent of students voting out of the total student population can be quite low, so a group of leftists can easily take control.
In the early 1970’s the Organization of Black Students, OBS, took over the student government at the University of Chicago. The group was well organized and got out the vote.
