Particularly John Sides and Joshua Tucker over at the Monkey Cage. The permanent link to the specific article I’m referring to is here. Basically, these guys in particular are pretty good about looking at the empirical evidence concerning whatever “trend” is being reported. They’re both very good at catching poorly researched, knee-jerk political “news” pieces, and they address the claims by looking at the actual facts and numbers, usually demolishing the argument of the piece. Johnathan Bernstein at “A plain blog about politics” is good on this as well, although he’s often focused on reversals of public statements by politicians (aka “flip-flopping”) which is also enjoyable but less “sciencey.” Anyway, hooray for Political Scientists!
