TAMPA, Fla. — And then there were two: Jane Castor and David Straz will head to a runoff to determine the city’s next mayor.

None of the seven candidates running for Tampa mayor, a successor to Bob Buckhorn, reached the 50-percent threshold to stave off a runoff election on April 23. Unofficial results show Castor leading with 47.99 percent of the vote.

Straz is in second with 15.47 percent.

Castor spent six years as the city’s police chief before putting away the badge in 2015. She was the first woman to hold the top post and the first openly gay one.

Hoping to win the top spot, Castor has campaigned on her experience in policing to promote a safer city.
