I’m with RitterSport on this. Trying to claim he “was using a facetious metaphor” for his off-his-rocker stupidity is about the lamest attempt at covering for a major “oops” I’ve ever seen.
I feel like he was trying to bait Kerry into saying: “Climate changed with out humans”, so he could say: “See? Told ya’, human caused global warming is a farce!”
His “gotcha” moment obviously didn’t go well for him.
