From November, 1998, through November, 2007, there was a slow rise in the Dem %, with a slight upward bump for the general election of 2004 (Kerry v. Bush). Also in 2004, there was a bump up for Others and down for R’s, suggesting perhaps some anti-Bush movement.

Dem registration continued its slow rise (perhaps this rising baseline is due to demographic factors) and then took a large jump with the primary (Obama v. Clinton) and general (Obama v. McCain) elections of 2008. Both R’s and Others contributed to that D jump.
