I'm posting this rumor mainly because it comes from someone with a long track-record in, and deep knowledge of, Washington State politics.
This person notes the recent time Dennis Kucinich has been spending in Washington State, notes that Kucinich has likely been redistricted out of a job in Ohio, and reminds that this state has a brand new district opening up in 2012.
The rumor is that Kucinich may be lining up a run for WA-10. It's a crazy rumor. But, my source adds: "He's just crazy enough to do it."
