New York Republican Chairman Ed Cox in a lengthy statement on Thursday insisted there was no “blue wave” for Democrats in last week’s off-cycle elections, but instead a series of local confluences that led to GOP defeats.

At the same time, Cox blamed high labor union turnout driven by a push to reject a constitutional convention for also playing a factor.

Republicans did not have a good go of it last Tuesday, losing both county executive posts in Westchester and Nassau as well as the Erie County Legislature. A Democratic candidate also won the Hempstead town supervisor’s post, a result that has been seen in a century.

New York City Mayor Bill de Blasio was handed a second term as he handily defeated Republican rising star Nicole Malliotakis.

For Democrats, this portends a big 2018, riding a crest in a blue state amid an unpopular Republican presidency.

But Cox saw bright spots for the GOP, including the re-election of Binghamton’s Republican mayor and Republicans winning county executive seats in Rensselaer, Rockland and Orange.

“Yes, we came up short in the Westchester and Nassau county executive races, and yes Washington did impact the suburban vote somewhat,” Cox said.

“BUT, local factors, like corruption issues in Nassau and third term ‘steppingstone’ to higher office issues in Westchester were factors as well. And a way underestimated issue was the Democratic union member turnout who were made fearful of a pension loss if the Constitutional Convention were to pass. We are grateful to Rob Astorino and Jack Martins who ran strong races. Their exemplary records of service and responsible government are not dimmed by the outcomes.”

Blaming the con con is at odds with the stance taken by Conservative Party Chairman Mike Long, who said in an interview last week the convention referendum turnout had little impact on the corruption issues in Nassau County. Long also acknowledged there was an impact by Democrats being energized to come out to vote after President Donald Trump’s election last year.

But Cox remains optimistic, he said, for next year.

“The 2018 election is our moment in New York political history and will be our chance to make New York again a fiscally sound, industrious, creative and prosperous state and as such the brightest light in that ‘shining city on a hill’ — The United States of America,” Cox said.
