ST. PETERSBURG, Fla (AP) — As Florida officials try to contain the spread of the novel coronavirus, the state’s voters will head to the polls and cast ballots in the Democratic presidential primary.

State health officials have been working with local supervisors of elections to make sure polling locations are safe and clean, and some precincts at nursing homes and senior centers have been moved.
