Democratic Sen. Elizabeth Warren of Massachusetts has endorsed Tom Perriello in the Virginia governor's race. Warren's endorsement means Perriello now has two of the leading progressive voices in the Senate backing his campaign: Sen. Bernie Sanders of Vermont endorsed Perriello earlier this month. Perriello is running an insurgent campaign against the state party's establishment pick, Lt. Gov. Ralph Northam, and has sought support from prominent national Democrats. The two will face off in a June primary. Virginia and New Jersey are the only states set to elect governors this year. Dem Terry McAuliffe is the current governor. As per the 1830 state constitution, VA governors may not run for a consecutive term (although they may run again later, and several have.)
