Hmm... I think I disagree with your statement that neither side has an inherent advantage. The Grayout fans are there for one reason: to vote NO on #1. They will vote Busta or some other freak as an afterthought, but they are going to search for and find the #1 question.
On the other hand, those debating here whether to vote for Arnie or Tom are most interested in that line, not the #1 question.
As I see it, there is a definite advantage to the true blue demodogs, and a real risk for this to be an important factor.
