Colorado Gov. Bill Ritter (D) announced Wednesday that he will not seek re-election in 2010.

Ritter, who won a four-year term in 2006, said at a news conference in Denver that he made an “intensely personal” decision to spend more time with his family.

“I’ve not made them the priority that they should be,” Ritter said. “So today I’m announcing the end of one of my roles: I’m no longer going to be a candidate for re-election in 2010.”
