NASHVILLE, Tenn. (AP) -- Partisan divisions over immigration, education and health care are intensifying as dozens of the nation's governors meet just months before elections thick with presidential implications.
The three-day gathering of the National Governors Association represents the group's final meeting before many state leaders face voters in an election season that will decide the balance of power in statehouses from Nevada to New Hampshire and could end some presidential campaigns before they begin.
New Jersey Gov. Chris Christie and Wisconsin Gov. Scott Walker lead a group of ambitious Republicans set to appear at the downtown Nashville conference opening Friday. Maryland Gov. Martin O'Malley is among the Democrats weighing a 2016 presidential run.
Another potential presidential contender, Vice President Joe Biden, addresses the conference Friday.
