Perhaps when the Republicans take over the house they can hold hearings on the state of free speech on college campuses. My dream would be that they tie federal support of colleges to campus free speech. There are metrics published by FIRE ( https://www.thefire.org/largest-ever-free-speech-survey-of-college-students-ranks-top-campuses-for-expression/ ) that have been tracking this for years, that could be used to incentivize colleges to change their policies to promote free speech.

In hospitals, Medicare requires certain clinical performance metrics be met in order to get Medicare reimbursement, and since Medicare is 40-60% of a hospitals income, it's taken very seriously, and drives change. If you look at the FIRE metrics, the best colleges still have very low free speech metrics. Requiring them to meet certain levels in order to realize their federal funding could drive significant changes on the campus.
