Huge gains.
Rhodes Cook analyzes new voter registration data in the 29 states where party affiliation is on record and finds that since 2004 the number of registered Democrats has grown by nearly 700,000 while the total of registered Republicans has fallen by nearly 1 million.
In addition, the "overall trend -- Democrats up, Republicans down -- is also mirrored in many of the states that already have been identified as battlegrounds for 2008. And with only a comparative handful of votes needed to swing key states such as Iowa and Nevada the Democrats' way, the latest registration numbers can only fuel the party's considerable optimism."
