Republican chairman in Broome and Chenango counties on Tuesday pledged to support state Chairman Ed Cox’s re-election amid a leadership challenge from Erie County’s Nick Langworthy.

“Ed Cox has my full support for State Republican Chairman,” said Broome County Chairman Bijoy Datta.

“He’s been a tireless advocate for our Party and has helped provide resources, organization and support to deliver countless victories in Broome County, the Southern Tier and across all of Upstate New York. Under Ed’s leadership, Republicans have won elections for Mayors, County Executives, District Attorneys, Judges and more – including plenty of areas where Democrats outnumber Republicans.”

Langworthy launched his bid to oust Cox from the leadership post on Saturday after Republicans last year lost control of the state Senate for the first time in a decade.

But Cox has received the public backing of large county chairs, including Westchester’s Doug Colety.

And the fault lines are not exclusively upstate-downstate in the leadership race.

“As the longest serving County Chair in New York State I have watched State Chairs come and go for many years,” said Chenango County Chairman Tom Morrone. “No one has been more committed to the position than Ed Cox. He works full-time, accepts no salary and is fully dedicated to party building and party unity.”

“As we enter the 2019-2020 election cycle we are facing new dynamics in campaigning including early voting, changes in campaign finance rules and voter registration. Ed Cox has and will continue to provide county parties with the tools needed to win election.”
