MoveRed.org is the youth coalition (ages 16-28) of the King County Republican Party. Their purpose is "to promote increased Republican activism among a younger segment of the population that is often left out of the political process." Above is their latest YouTube video.
I'd love to see a group like this started up in Whitman County. In Pullman, at least, the conservative youth voice is often suppressed/squelched/ignored by liberal teachers and professors.
