4,098 of the total 5,445 primary ballots were early voters and 2,800 of those were by mail!
The article states 55% of the registered voters...
The high turnout was in the local races, deport. I guess they were trying to keep a low profile.
"In local Duval County races, turnout was more than five times the state average, with 5,533, or 55 percent, of the county's 9,839 registered voters turning in the county judge's race and 5,317, or 54 percent, voting in the treasurer's election, according to election returns."
