McFarland has already been on Fox. I wasn't impressed.
I'll put my money on John Spencer.
The trouble with the RINO cows is they unilaterally abandon (a la Pirro) the most important truth telling attacks they can make on the Witch, leaving each with no campaign at all.
One of the neat things about running Spencer is that it looks like the Witch will win no matter who runs against her. Thus, Spencer has nothing to lose and he can run the first truthful, hard-hitting, negative campaign in history against a Clinton.
