Bill Richardson: Libertarian Democrat

Liz Mair (via Dave Weigel):

Richardson scored third best of any Democratic governor for overall current-term performance on Cato's 2006 Fiscal Policy Report Card on America's Governors. He earned a better grade than 37 other Governors, including 20 Republicans, in part because, during his tenure, New Mexico's top marginal income tax rate has dropped a remarkable 35%.

Mr. Richardson also brings good credentials where immigration, guns, and social issues are concerned. He declared a border emergency in his state in 2005 (so he's no immigration softie), and he voted against the Brady Bill and other gun control initiatives while in Congress. Yet, Mr. Richardson also has solid, moderate, pro-choice credentials, and is not a proponent of constitutional bans on gay marriage or civil unions.
