If Democrats go down this road, their only way forward will be to one-up each other in every primary election. Clueless liberals such as Facebook co-founder Chris Hughes want to guarantee $500 per month for every American earning less than $50,000 a year. But why not $550? Or should we go ahead and call it an even $600? A guaranteed monthly stipend would become the floor. And every subsequent election would be a referendum on whether voters want to support the candidate promising the larger pay raise from Washington. Is that where we want our elections to go?

Anyway, Clinton’s admission of the Democrats’ matter-of-fact acceptance of socialism couldn’t have been any timelier. Saturday marked the bicentennial of Karl Marx’s birth, and as Paul Kengor reminded us in his smart Wall Street Journal commentary last week, Marx’s communist philosophy “set the stage … for the greatest ideological massacres in history.” Marx’s rebuke of capitalism and individual property rights inspired the likes of Vladimir Lenin, Leon Trotsky, Mao Zedong, the Kim family, the Castros and countless others to wage mass murder against millions of innocents.

But never mind that, at least according to many of today’s millennial voters.
