One more from the Pledge: the Catch goes to TNR's Alexander Hart, who noticed some funny business in the way the Republicans scaled a key graph in the Pledge. Paging Andrew Gelman! Plain Blog policy prevents me from showing it to you, but that's OK; you'll want to click over to it anyway. Nice catch!
(I suppose I should say in the spirit of full disclosure that Hart's post appears at Citizen Cohn, and while I'm not sure I've mentioned it here, I've been crossposting an item a day to Jonathan Cohn's blog. Nevertheless, I assure you that we here at Plain Blog maintain a rigorous firewall (note intentional awkward wording) between our "catch of the day" department and our "get people to read more Bernstein" department).
