Holy hornet’s nest, Batman! The New Mexico governor’s mansion? Fresh from the inauguration, actor Val Kilmer is pondering running for governor in 2010, when two-term Democrat Bill Richardson will be forced from office by term limits. “I’m just looking for ways to be contributive,” Kilmer told The Associated Press on Thursday. “And if that ends up being where I can make a substantial contribution, then I’ll run.” But there’s no decision yet. “It’s really day to day,” he said over tea at a local restaurant. Kilmer, 49, grew up in Los Angeles but has called New Mexico home for more than two decades. He’s currently registered as a Democrat and said he cast a ballot for Barack Obama from Bulgaria, where he was filming. A Kilmer candidacy could throw a monkey wrench into the well-oiled Democratic machine of Lt. Gov. Diane Denish, who’s already running for the job.
