Here's a look at the results of some of the races around the Tampa Bay area.
In Pasco County, voters decided to keep one incumbent commissioner and get rid of another.
Henry Wilson Jr., a 37-year-old Republican health care manager, defeated the board's lone Democrat, Michael Cox, who was running for a second four-year term on the commission.
Wilson, a political newcomer, said he wants to make the county friendlier to small businesses. He won 52 percent of the votes for the District 4 seat.
Cox, a 46-year-old financial planner, was one of the county's most high-profile commissioners and is widely credited with helping land financial firm T. Rowe Price and getting the county to devise strategic and business plans.
Meanwhile, chairwoman Pat Mulieri, a Republican, won her fifth term on the board with 70 percent of the vote against longtime environmental activist Clay Colson, who was running without party affiliation.
Mulieri, a 72-year-old retired English professor, has said this will be her final term on the board.
Republicans also did well in Hillsborough County.
There, incumbent Mark Sharpe was handily beating challenger Cornelius "Neil" Cosentino for the District 7 seat late Tuesday night. As of 10:30 p.m., Sharpe had 71 percent of the vote.
Current Commissioner Ken Hagan, who held the District 2 seat representing northern Hillsborough, appeared headed for the at-large District 5 post. He was beating Democrat Linda Saul-Sena, a former Tampa City Council member. Hagan had 53 percent of the vote at about 10:30 p.m.
Victor Crist was easily beating grass roots activist Steven Morris, who was running without party affiliation, for the District 2 seat. Crist owned about 72 percent of the vote late Tuesday night.
And Sandy Murman, a former state representative, appeared headed to victory over Democrat John Dingfelder, a former Tampa City Council member, for the District 1 seat. She had 54 percent of the vote.
Republican James William Grant, a lawyer, also was winning the seat for District 47, which covers northwest Hillsborough County.
Grant, who was up against Democrat Michael Steinberg, who also is a lawyer, had about 69 percent of the vote as of 10:30 p.m.
Grant, the son of former state Sen. John Grant, beat a legal challenge launched several days ago by Hillsborough County Democrats to force him to produce bank records.
Meanwhile, the Florida Elections Commission has agreed to investigate the charges that Grant accepted donations fewer than five days before the primary election, as well as an allegation that he received a donation in excess of the $500 state limit.
