Change Is Inherent In Elections

|
Apparently there was another GOP debate tonight. Did you know? I'll watch tomorrow maybe but in the mean time I smiled at this remark from Jim Geraghty's liveblog:
Thompson comes out and says the obvious - that all the talk of "change" is a reaction to Iowa, and that change is an inherent part of any election. "I think what is more important is leadership."

Fred Thompson talks as if he's polished off a tall glass of truth serum before he sat behind the desk tonight.

Does he mean Thompson's somnolent? Or just that he's playing no games?
