Earmark crusade

Over at Reason, Radley Balko gives credit to Republicans who fight earmarks, while attacking "national greatness conservatism":

In fact, the few actual libertarian-leaning Republicans left—Reps. Jeff Flake and Ron Paul and Sen. John Sununu, for example—have led the charge to reform the corrupt earmarking process.

Come to think of it, there's another prominent Republican who's been vociferously opposed to earmarks for years. Anyone remember the name?
