I remember Zach Wamp speaking to us at a leadership seminar back in 11th grade about how he supported term limits and about how he was going to bow out of politics when after his term had expired. I'm now 25+ years old. ;) I think that answer may have been more of a Q&A-type scenario than the focus of his speech.
I don't at all hold it against him for hanging on, but it still kind of amazes me to see the guy still around.
I was one of the voters that put Wamp into office back in '94. I am actually glad that he has stayed. I think he would make a terrific senator for TN.
