Where Republicans have gained in voter registration ahead of November

Florida, a longtime battleground state, has slipped safely into Republican hands in recent cycles. At one time, Democrats dominated Republicans in the state regarding the number of registered voters. The yawning gap in 2012 was a 557,544 advantage in favor of Democrats.
