If his presence is related to his radio gig, you can sue the radio station too!
We freepers have the liberal moron rants down pat, we can imitate 'rats in our sleep. Getting past his call screeners is going to be a snap, then turning on him or making liberals sound like the fools they are is going to be a lot of fun.
For example: a "proud gay man" calls to support gay marriage, and then goes on to expound on his preference for Boy Scouts, and the unfairness of not being allowed to be an openly gay Scoutmaster.
Or a "pro choice" caller who graphically supports partial birth abortion in terms that would make Doctor Mengele proud. And so on.
It's going to be almost too easy driving Franken mad. (He's just about there already.)
