Mr. Shumlin is a Democrat, and the bill’s passage is a credit to his party. Yet a small upstart spent years building support for reform and nudging the Democrats left: the Vermont Progressive Party. The Progressives owe much of their success to the oddities of Vermont politics.

(Mr. Sanders is an independent, but a longtime ally of the Progressives.) “If Vermont can be that model it will have a profound impact on discourse in this country.”
