Assemblywoman Grace Meng of Flushing handily defeated three Democratic opponents Tuesday in the 6th Congressional District primary.

The unofficial count was 51 percent for Meng, 28 percent for Assemblyman Rory Lancman of Fresh Meadows, 16 percent for City Councilwoman Liz Crowley of Middle Village and 5 percent for Dr. Robert Mittman of Bayside.

It’s official — Rep. Bob Turner (R-Queens, Brooklyn) will have to find another line of work in January, or go back to retirement.

Turner, who won the 9th District congressional seat in a special election after former Rep. Anthony Weiner resigned, lost his bid to be the Republican nominee for U.S. Senate on Tuesday. He wanted to challenge Sen. Kirsten Gillibrand (D-NY) in November, but was easily defeated by Wendy Long, an attorney in Manhattan.

Candidates seen as the front runners in congressional primaries across Queens — whether incumbent lawmakers or party establishment choices — all won their nominations by wide margins Tuesday, according to preliminary results.

Democrats in much of Queens — and Republicans across the entire borough — will go to the polls June 26 to vote in primaries for their party’s nominees for Congress.

On the Republican side, the race pits U.S. Rep. Bob Turner (R-Queens, Brooklyn) against Manhattan attorney Wendy Long and Nassau County Comptroller George Maragos, who each are seeking the nomination to run against Sen. Kirsten Gillibrand (D-New York) for a full six-year term. Republicans across the state will be voting in the primary.

U.S. Sen. Kirsten Gillibrand (D-N.Y.) has a pretty cushy lead over her three Republican challengers, including U.S. Rep. Bob Turner (R-Queens, Brooklyn), according to a Siena poll released this week.

“With a two-to-one favorability rating, and a majority prepared to re-elect her, [Gillibrand] continues to look strong seven months from her first re-election attempt,” said Siena pollster Steve Greenberg.

He made it by the narrowest of margins, but Congressman Bob Turner (R-Queens and Brooklyn) will be on the June 26 ballot for the Republican primary for the U.S. Senate.

Turner garnered just over the 25 percent of the vote necessary at the Republican State Convention last Friday.
