In 2008, voters under 30 preferred Barack Obama over John McCain by a 66 to 32 percent margin. Among older voters, Obama led McCain, 50-49.

Mead is not a tea party crazy or Ayn Rand zealot. He is a history professor at Bard College and an expert on American foreign policy. He voted for Obama in 2008, and he’s not wild about Mitt Romney now.
