As usual, I could be wrong. But hasn't FOX NEWS offered Crazy Uncle Bernie on for a town hall? Same with Creepy Joe. And they refused the invite, as far as I know. (Editing to add, Creepy Joe DID go on Chris Wallace, but thought his name was Chuck.)
If one wants to "reach out to both sides", shouldn't both Dems and Republicans do such a thing? Ralph for one would welcome that.
