Janice Brown at Cow Hampshire, inspired by Daniel Henninger's observation of Justice Souter's "stiff, slightly scary New Hampshire stare", has come up with an entertaining article, accompanied by a poll allowing you to vote on the scariest stare from a selection of Granite Staters.
From her choices, I think it's pretty clearly John Stark, but don't let that influence you; get over there and express your opinion.
I'd like to put in my own plug for our ex-Congressman Norm D'Amours, pictured above. Still crazy after all these years.
