Republican state Senate candidate Aaron Bean defeated Democratic challenger Nancy Soderberg in a battle for District 4.
Bean received 62 percent of the vote
"I cannot thank the voters enough for all the support they have shown for our campaign for Senate District 4," Bean said. "Since Day One, I have campaigned on creating jobs, providing more choices for parents in their children's education and bringing a marketplace of affordable health care to all Floridians; and now, I have the privilege and opportunity to deliver on these principles for our First Coast region."
After the redistricting process earlier this year, Florida Senate District 4 now covers about half of Duval County and all of Nassau County.
Bean, a veteran Republican state representative, won a grueling and expensive primary battle with Rep. Mike Weinstein to advanced to face off against Soderberg.
"Nancy Soderberg started a new conversation on the issues that matter to our area the most -- jobs and education," a spokeswoman for the candidate said in a statement. "She fought hard for our First Coast families and will continue to fight for our Florida families. We congratulate Aaron Bean on his victory and know he will give his best effort for the people of northeast Florida."
