Polls are now open on this Primary Day in Florida.

Voters are deciding key match ups, including who will represent Central Florida in Congress.

There are big changes this election because congressional maps were redrawn last year after the state legislature lost a court battle.

Several Democrats are running in two U.S. House of Representative Races, hoping to move on to the general election.

Congressman Alan Grayson is not seeking re-election in District 9 since he's running for U.S. Senate.

Instead his wife, Dr. Dena Grayson, is running against Susannah Randolph, a former community organizer and congressional office worker. State Senator Darren Soto is also running, along with college professor and former chair of the Democratic Executive Committee in Osceola County Valleri Crabtree.

The winner will face Republican Wayne Liebnitzky, a St. Cloud businessman, or Wanda Rentas, current vice mayor for Kissimmee, in the November election.

Up in District 10, four more Democrats are looking to replace Republican Congressman Daniel Webster, who is seeking re-election in District 11 because of re-districting.

Former Orlando Police Chief Val Demings, State Senator Geraldine Thompson, former Democratic Party Chairman Bob Poe and Orlando lawyer Fatima Fahmy face off in the Democratic primary.

The winner goes against Republican Thuy Lowe in November.

In District 11, Webster will face off against Justin Grabelle in the Republican primary.

The winner takes on Democrat Dave Koller and Independent Bruce Ray Riggs in the general election.

Polls are open until 7 p.m.
