In 2012, there was 755,000 total votes cast in Broward which is a Democratic stronghold. Here it is 2016, they have counted 620,000 votes in Broward county, and CNN says Broward has only reported 16%. So either:

A: There are now 3.8 million registered voters in Broward county, which means they increased their voters by 3 million in 4 years

B. CNN is a joke who can't address an obvious error that any one on their team with 3rd grade math skills could have spotted.
