Each is a former two-term Republican governor in a Democratic state who got the local economy moving. Governing across party lines means each is comfortable at compromise, a spirit at the heart of their quixotic campaign. Johnson and Weld aren't running as anti-government-free-will Libertarians with a capital L. They are agile, practical-minded thinkers with a few quirks: Conservative on money issues, socially liberal, skeptical of government power and military entanglements. Not so scary, right? "Most people are Libertarian," Johnson told us. "It's just that they don't know it."
