I did not hear him campaign for Romney during the primaries. If he campaigned for anybody, it was Rick Santorum.
You are correct. I listen to Glenn everyday. He was for Santorum and Bachmann. He gave Santorum and Bachmann lots of airtime. He also had other conservative candidates from state and US congress races on to give them good exposure.
He only backed Romney because he was NOT ZERO! The previous poster on this thread who said Glenn actively campaigned for Romney, certainly didn’t listen to his show!!
