New Yorkers go to the polls Tuesday for the state's final primary elections and two races for state offices will be closely watched.

In Lower Manhattan, six Democrats are vying for the party’s nomination to run for the Assembly seat formerly held by speaker Sheldon Silver, convicted on corruption charges late last year.

Alice Cancel won the special election in April to serve the remainder of Silver’s term. Several of the former speaker’s supporters backed Cancel in the election.

She now faces challenges from five other candidates for the seat: Paul Newell, a community activist who ran against Silver in the 2008 primary;  former assemblyman aide Yuh-Line Niou, who narrowly lost to Cancel in April; civil rights attorney Jenifer Rajkumar; former community board chairwoman Gigi Li; and businessman Don Lee.

The district is a Democratic Party stronghold, so the winner of the primary race is all but certain to be elected in November.

In the other must-watch race, four Democrats are contending for the state Senate seat formerly held by Adriano Espaillat, who won the June primary to succeed Congressman Charles Rangel.

Marisol Alcantara, an activist with the New York State Nurses Association, is Espaillat’s choice for the seat and has the backing of the Independent Democrat Conference, which has aligned with senate Republicans.

She faces tough opposition in a field that includes Micah Lasher, a former top aide to Attorney General Eric Schneiderman and former Mayor Michael Bloomberg; former City Council Member Robert Jackson; and community activist Luis Tejada.

Statewide, 65 Senate seats and 150 Assembly seats will be contested in the November elections.

Only registered Democrats and Republicans can vote in Tuesday’s primary.
