Connecticut Democrats endorsed Ned Lamont to run for governor during their convention last weekend in Rocky Hill.

The GOP endorsed Danbury Mayor Mark Boughton at its convention at Foxwoods last weekend, but a number of candidates are petitioning for a primary.

Lamont is joined atop the ticket by former Secretary of the State Susan Bysiewicz, running for lieutenant governor. The positions of governor and lieutenant governor are elected separately in Connecticut.

“It was a great day to be a Democrat from Darien and from Fairfield County,” David Bayne, chairman of Darien’s Democratic Town Committee, said. “Not only is our nominee for governor Ned Lamont an extraordinarily successful Greenwich businessman, who is ready to put his skills to work for the people of Connecticut, but Darien’s own state representative, William Tong, is poised to follow in the footsteps of Fairfield County natives Richard Blumenthal and George Jepsen as attorney general.”

Lamont ran for U.S. Senate in 2006 as the Democratic candidate, losing to Sen. Joseph I. Lieberman, who ran as an independent. Lamont lost to the man he could replace, Democratic incumbent Gov. Dannel P. Malloy, in a 2010 gubernatorial primary.

Bysiewicz, who served as secretary of the state for a dozen years, attempted to run for governor, then attorney general, both in 2010, only to be disqualified from the AG race for not meeting job requirements. She lost a primary to U.S. Sen. Chris Murphy in 2012.

The endorsed candidates could still face challenges from within the party.

Lamont may face a primary challenge. Bridgeport Mayor Joseph Ganim, who failed to get the 15% of delegates needed to automatically qualify, has said he may petition his way onto an August ballot. Guy Smith of Greenwich could also enter a primary but did not participate in the convention, according to published reports.

Eva Bermudez Zimmerman earned enough delegates to be in a primary with Bysiewicz for her spot on the ballot.

Chris Mattei qualified for a primary against Tong.

As a first-time candidate for public office, I am incredibly humbled by the support of so many delegates who cast a vote for me today in Hartford, and resoundingly put us on the ballot for the August primary,” Mattei said in a statement. “I also want to congratulate Rep. Tong on receiving the endorsement and look forward to a primary with him and Sen. Doyle focused on the issues that Connecticut voters care about.”

Bayne said Darien Democrat delegates unanimously supported Ned Lamont for Governor, Susan Bysiewicz for Lt. Gov., Darien's own William Tong for Attorney General, Denise Merrill for Secretary of the State, Kevin Lembo for Comptroller, and Dita Bhargava for Treasurer. 

“When Dita withdrew in the second round of voting, all ten of Darien's votes went to Arunan Arulampalam.  Of course, we were all excited to nominate Chris Murphy for U.S. Senate on Friday night,” Bayne said.

Both parties would hold primaries Tuesday, Aug. 14.
