Greer should be pilloried and then run out of the Republican party. We should look into ways to get him expelled from the party and work nationally to get him defeated in the '06 election. We as a party have the right to censure him.
His country and state organizations should immediately move to disassociate with him. And they probably already have.
Greer will almost surely not be running for re-election - disgraced if not de-barred. There should be other candidates quickly forthcoming.
He is not a judge and he is not a Republican. He is a long-time opportunist. And vile. Period.
