Polls opened at 6 a.m. Tuesday across Long Island for more than 150 local elections, led by Nassau County executive and Suffolk County district attorney — two races in which the departing incumbent is facing federal corruption charges.  In all, 306 candidates are running in 155 county, town, city and judicial races in both counties. Nassau has 125 candidates vying for 55 elected positions; Suffolk has 181 candidates competing for 100 seats.  

Statewide, voters also will decide on three propositions, including whether to hold a constitutional convention that could change state government and whether to allow judges to revoke or reduce pensions of officials convicted of corruption crimes.

Suffolk's highest-profile race is for district attorney. It features Republican Ray Perini, a veteran criminal defense attorney and former narcotics prosecutor; Democrat Timothy Sini, the Suffolk police commissioner and a former federal prosecutor; and Libertarian Party candidate Christopher Garvey.
