Via Kudzu Files. A 17 year old guy's been blogging as The New Democrat since November. Along comes a former Swift Boat Veteran supporter, "Ricky Vandal," who starts a blog with the same name, except with the added tagline "Saving the Democratic party from the looney left." Centerfield was the first to try to help and has the details. Now lots of blogs are talking about it.
UPDATE: Happy ending.
Um...actually centerfield wasn't the first.
Why Are We Back In Iraq? and Loaded Mouth are where to look for more info.
