The Newtown, Conn., shooting has prompted a handful of states to enact tougher gun laws, and blue-state governors have led the way.
With Congress yet to agree on any federal changes, Maryland Gov. Martin O'Malley and New York Gov. Andrew Cuomo—both thought to be Democratic presidential contenders in 2016—have shepherded tighter restrictions in their states. In Connecticut, Democratic Gov. Dan Malloy signed a new gun law earlier this month.
Add Chris Christie to that list.
