For the same reason you've gone quiet about Trump: Boycotts.
In a boycott, Levin loses listeners by the truckload.
In a boycott, you ride the zot lightning off Free Republic.
So you are saying if Trump is not pro-Sanders he would get boycotted?
A lot of these radio hosts and commentators are going to find their careers in a world of hurt by the end of next year when they are exposed as having knowingly supported a liberal coup.
A lot of Freepers used to complain about liberal professors who would silence conservatives. Now you actually proudly proclaim you want conservatives silenced. Good luck with that.
