Do you think the Armor voters will vote for Shuler?
In any case, to speak to the topic of the thread, I will be extraordinarily surprised if Taylor resigns. The way Taylor wins tough elections is he waits until the last six weeks and then dumps however much money into his campaign that he needs to win, and to date it's worked. I rather doubt he'll see himself as more vulnerable than in 2000 and 2002 when he had major allegations of tax evasion (though Sam Neill was a far inferior challenger).
Besides that, however, I would venture that John Armor (Billybob) is gonna have a really huge uphill climb to push Tom Apodaca, Wilma Sherrill, Nathan Ramsey, Carl Mumpower, Joe Dunn, etc, etc out of the way for the GOP nomination if it comes open.
