Yglesias points to the new Tax Policy Center report on Newt's tax plan, and provides some handy graphs. He missed the obvious thing though, which is to give it the treatment CBPP gave to Herman Cain's plan.

UPDATE: Though I did spend about 12 seconds on Excel making this thing, obviously feel free to spread it far and wide. It did take me far, far longer to figure out how to make the picture appear full resolution. Blogger kept resizing it to an unreadable degree, as did Flickr and Photobucket. Finally Imageshack did the trick. They've got an option there to upload full whack, without any alterations, and then an embed function. Good to remember!
