WEST HEMPSTEAD - Voters will head to the polls Tuesday to pick their candidates in several primary elections, including the wide-open 4th Congressional District.

Two powerful Nassau names are vying to be the Democratic candidate in that race. Nassau County District Attorney Kathleen Rice and Nassau Minority Leader Kevan Abrahams are facing off with hopes of succeeding retiring nine-term Rep. Carolyn McCarthy (D – Mineola).

McCarthy has voiced her support for Rice, who was a heavy underdog in her victory in the 2005 district attorney's race. Voters re-elected Rice in 2009 and 2013, both years in which Republicans largely dominated countywide races.

Kevan Abrahams is hoping to become the first African-American to represent the 4th District in Congress. He's served in the Nassau County Legislature for over a decade, and believes his experience working within the confines of a legislative body will enable him to navigate the peaks and valleys of Capitol Hill.

However, Abrahams’ campaign has been outspent by a more than 5-to-1 margin. It’s why he says he has been out on the streets, meeting face-to-face with potential voters.

The Republican primary for the 4th District pits former Nassau County Presiding Officer Bruce Blakeman against attorney Frank Scaturro.

The 4th District has more registered Democrats than any other district on Long Island.
