He was on Fox News talking to Greta Van Susteren last night.
Looking for that, I ran across this Crooks and Liars post, dated April 5th, complaining about Prosser appearing on Greta's show the night before the election. The blogger, John Amato, states a principle of ethics that you know damned well he wouldn't apply generally. Keep in mind that both Prosser and Kloppenburg were invited onto the show, and Kloppenburg declined. Here's Amato:
I think it's inappropriate and unethical for Fox News to have candidates for public office on the night before an election, because it's a clear attempt to manipulate the election results. Prosser gets to throw bricks at Kloppenburg for free -- including defending himself on accusations that he failed to prosecute a child-abusing priest...
Greta brought up the dirty story of Prosser calling the Chief Justice of the Wisconsin court a "bitch' and threatening to "destroy her". Watch how [Greta] phrases the events. Calling the Chief Justice a bitch is not as bad as having somebody snitch on you. ya know. It was all a TRAP to ensnare him! Right.So... Prosser got a chance to defend himself from the vicious attacks, and no one was there to push back from the attack side, because Kloppenburg didn't have the nerve to enter the scary enemy territory that is the Greta Van Susteren show. And in Amato's view that is "inappropriate and unethical." Ridiculous.
