TALLAHASSEE, Fla. (AP) — More than one million voters have cast ballots in the state's crucial primary election.

The Florida Division of Elections website says that more than 861,000 voters have mailed in their ballots so far. Nearly 163,000 people have voted at early voting polling places.

Early voting is under way at all 67 counties.

Florida's primary is Aug. 28.

The top races are the gubernatorial primaries but there are also Cabinet primaries as well as many contested congressional races.

Former U.S. Rep. Gwen Graham, former Miami Beach Mayor Philip Levine, Tallahassee Mayor Andrew Gillum and businessmen Jeff Greene and Chris King are the Democratic candidates for governor. Agriculture Commissioner Adam Putnam and U.S. Rep. Ron DeSantis are the Republicans.

There are more than 13 million registered voters in Florida.

More than 1.8 people voted early or by mail in the 2016 general primary, and over 2.1 million in that year's presidential primary. More than 1.2 million voted early or by mail in the 2014 mid-term primary.
