Sorry, that was my mistake. It was Lucas who has had the recent missteps, not Davis. For some reason, I keep mixing up the candidates in this particular race. Maybe it's the bland two-syllable names both of them have. :)
If you're still interested in Lucas' missteps, his people have stolen signs, he indicated he might challenge Jim Bunning in 2004, and despite not being invited to President Bush's speech in Cincinnati (Davis was), he showed up anyway (InvitationGate, they're calling it).
Given that I had attributed the missteps to the wrong candidate, I guess I would have expected slightly closer numbers.
