For all of Obama's post-partisan rhetoric and recent "moves to the center," the truth is that self-identified Democrats will represent the majority of Obama's improvements on Kerry's vote totals.
According to Rasmussen, Democratic self-identification has increased by 3.5% since November 2006, when Democrats made up 38% of the electorate. If Democrats make up 41% of the electorate in 2008, Republicans drop to 33%, and partisan vote preferences break just as they did in 2004, then Obama wins 51.2%--47.7%, without doing even one point better among Republicans or Independents. That is a net 6% improvement on Kerry's result, and it would come entirely from the creation of new Democrats.
If Obama wins 89% of the Democratic vote, and if Democrats make up 41% of the electorate, then Obama will have to win 64% of the Independent vote in order for his gains among Independents to equal his gains among Democrats. Given that such a victory among Independents is extremely unlikely, it can be said with real certainty that Obama will improve on Kerry's vote totals more from self-identified Independents than from self-identified Democrats. Right now, about the only thing that could prevent that is if there is a collapse of Democratic self-identification between now and November.
Given the huge gains that can be made just from Democrats, running on a partisan brand seems like a very good idea now. That goes not only for Obama, but for all Democratic candidates. We need to identify with the brand to help build it up and, in return, the newly dominant brand will carry us to victory. |
