If only Britney Spears fans were allowed to vote, Kerry would have won in a landslide. Most Britney fans are young, and young people are more Democratic. The majority of Britney fans are girls and gay men, also Democratic constituencies. Very few Britney fans are part of the Religious Right due to her revealing outfits. Expect the majority to be in the bottom half of the political compass.
Kerry would have won in a Reagan-like landslide. Bush would have won Maine (a strange state where younger voters are more Republican than older voters), Utah, and Idaho.
Britney declared that we should support the president, though.
