“This is the first election where we really get to see libertarians make excuse after excuse for their candidate’s heresies,” NRO contributing editor Dan Foster tweeted Wednesday night. “It’s humanizing!”

Anyone familiar with the typical behavior of capital-L Libertarians understands exactly what Foster meant, and why his comment was funny. For years, libertarians have been too cool for school. More precisely, they’ve been too cool to engage in real politics or anything related to what is politically possible. They’ve been especially loath to support electable candidates of any kind. Even Republicans who have seemed a bit libertarian at heart have usually been too impure to win their support.
