Gallup reports that 84% of Republicans approve of Bush's performance versus just 16% for Democrats -- the widest gap in this category in 56 years of tracking it. It helps to point out 1) just how polarized the country is, it's unprecedented (recall, GW The Uniter), and 2) assuming 84% of Dems (inverse of 16%) disapprove of Bush's performance, we have 84% vs. 84% potentially meaning -- as mentioned here before -- that Bush & Kerry are fighting over about 16% of available votes.

It's another reason why a Howard Stern or Ralph Nader influence, for example, truly matters this time around.
