FIVE PEOPLE SHOT ON MARDI GRAS PARADE ROUTE IN NEW ORLEANS: 1 DEAD, SUSPECT DETAINED
Two Democrats are making a runoff in a Louisiana House special election on the Saturday before Mardi Gras.
The District 93 seat represents Uptown, Downtown and parts of the Garden District and is reliably Democratic.
It has been vacant since Royce Duplessis was elected as a state senator and was sworn in in December.
Prior to Duplesis the seat was held by Karen Carter Peterson, who went on to serve as the state Democratic party leader. Last year Carter pleaded guilty to wire fraud and was sentenced to 22 months in prison.
The election fell on the Saturday before Mardi Gras, and numerous parades rolled through the district as voters went to polls.
