This may be ggod theater, but I think it makes for bad politics. Whether it is true or not, few voters will really believe that Simon is doing this for reasons of "open debate." That makes him appear cynical.
It's a juvenile move. It's OK for FReepers to sprinkle Camejo stickers about because that doesn't appear associated with a conservative tactic, but that doesn't mean that Simon should be seen doing it.
I disagree. Simon is effectively calling more media attention to a debate that was set up by Davis to get the least amount of attention as possible. It's also reinforcing Davis' fear of debating Simon, hopefully making undecided voters question what Davis is hiding from. I also imagine this ticks off Grayout, who is always just one question away from losing his temper. Definite bonus points if Simon can get Davis to throw a tantrum.
Unless Simon is foolish enough not to show up, then I'll agree it was a poor decision.
