The United States is living through an era of unprecedented elite failure, in which America’s public institutions are understandably distrusted and our leadership class is justifiably despised. Yet politicians of both parties are required, by the demands of partisanship, to embrace the convenient lie that our problem can be pinned exclusively on the other side’s elites — as though both liberals and conservatives hadn’t participated in the decisions that dug our current hole.

In this climate, it sometimes takes a fearless crank to expose realities that neither Republicans nor Democrats are particularly eager to acknowledge.

In both the 2008 and 2012 campaigns, Paul has been the only figure willing to point out the deep continuities in American politics — the way social spending grows and overseas commitments multiply no matter which party is in power, the revolving doors that connect K Street to Congress and Wall Street to the White House, the long list of dubious policies and programs that both sides tacitly support. In both election cycles, his honest extremism has sometimes cut closer to the heart of our national predicament than the calculating partisanship of his more grounded rivals. He sometimes rants, but he rarely spins — and he’s one of the few figures on the national stage who says “a plague on both your houses!” and actually means it.
