The Libertarian party seemed to have a once-in-a-generation opportunity this cycle. The public hates both the major-party nominees, and Gary Johnson, a former governor of New Mexico, seemed to fill a real niche.

But he’s blowing it. He’s had a series of gaffes in recent weeks, especially over foreign policy. More broadly, Johnson’s campaign lacks any coherent theme to attract disaffected partisans from both sides. And his only real shot at viability was to make it into the debates, but his polling numbers were too low for the minimum threshold.
