The race to represent Florida Senate District 34 is down to two candidates.
Republican Joseph Bensmihen dropped out of the contest Thursday, state records show.
That leaves just Maria Lorts Sachs, the Democratic incumbent; and Ellyn Bogdanoff, a Republican who served a previous term in the state Senate.
Bensmihen, a Palm Beach County businessman, had raised more than $12,000 for his campaign, records show. He loaned himself an additional $100,000.
It was not immediately clear why Bensmihen withdrew. He did not return calls Friday.
Bogdanoff has said Bensmihen supported her in the past.
The Sachs-Bogdanoff race will be a rematch of the 2012 election. In that race, Sachs defeated Bogdanoff by five percentage points.
Senate District 34 includes parts of Broward and Palm Beach counties.
