In a special election on Tuesday, voters in southwest Miami-Dade County will determine the successors for two seats in the state Legislature that opened up after a Miami Republican senator was forced to resign last spring when he made racist and insulting remarks in front of fellow senators at a bar near the state Capitol.

The fight for the District 40 Senate seat — formerly held by Frank Artiles, who stepped down in April — has been highly competitive for what it could mean, particularly for Democrats: The chance to flip the seat and narrow Republicans’ current 24-15 advantage in the chamber.

The House District 116 seat is also on the ballot, because Florida’s “resign to run” law required Miami Republican state Rep. Jose Felix Diaz to vacate that seat when he chose to run in the District 40 contest.
