In the race for the Democratic party nomination to run for the county legislature’s 17th district, insurgent candidate Oquendo-Thomas holds a 49.65 percent to 50.30 percent margin over her opponent, party-endorsed Wilson A. Terrero. Absentee ballots, which must be postmarked on election day, can be received and counted until Tuesday.
