ORLANDO, Fla. (AP) - Democratic Sen. Bill Nelson of Florida has won a third term after defeating Republican Congressman Connie Mack.
    
The win will go a long way to helping Democrats try to keep control of the U.S. Senate.
    
The 70-year-old Nelson won even though he was up against the son of Florida's former U.S. Senator. Mack is also named after his great-grandfather, a baseball Hall of Famer.
    
The victory continues Nelson's 40-year political career and ends, for now, the political career of Mack. He had been representing southwest Florida in Congress.
    
Nelson portrayed himself as a moderate during the campaign while Mack tried to tie Nelson to President Barack Obama by noting his votes for the stimulus and health care overhaul.
