From Jacksonville Times:

Since a new set of state voting laws went into effect more than a year ago,  the number of new Democrats registering in Florida has all but disappeared,  according to a Times-Union review.

During the 13 months beginning July 1 the year before elections in 2004 and  2008, registered Democrats increased by an average of 209,425 voters. From 2011  to this year, that number was 11,365.

In Duval County alone there were about 13,000 new Democrats, meaning the rest  of the state lost them.

Over that same time, the number of registered Republicans increased by  128,039, topping the average of 103,555 during the past two presidential  cycles.

Overall, Democrats still hold a 445,794 statewide registration advantage.
