Contention developed between two different groups, one supportive of Lieberman and one critical of him, with each faction asserting that it controlled the party.
On August 9, 2006, the day following the primary, Lieberman supporter Stuart R. Korchin changed his party registration to Connecticut for Lieberman. The change was not entered in the state's electronic voter database, however.
On November 15, 2006, John Orman changed his party registration from Democratic to the Connecticut for Lieberman Party, having been told by the Secretary of State that there were no registered party members. Orman, a professor of politics at Fairfield University, had briefly challenged Lieberman for the Democratic U.S. Senate nomination in 2006.
Party rules were filed with the Connecticut Secretary of State Susan Bysiewicz on December 21, 2006 by Orman. According to Ted Bromely, a state elections attorney who works for her office, then said, "If someone wanted to challenge it, they'd have to go to court.
On January 12, 2007 Korchin filed a different set of party rules with the Secretary of the State, which were also accepted. In response to an inquiry, Korchin received a letter from a lawyer in the Secretary of the State’s office on January 17, 2007 stating that the state had "very limited jurisdiction" over intraparty battles, and was not taking a position over just who was in charge.
In March, Korchin changed the Wikipedia article about the party to reflect his role and in response to Orman's claims.
In Milford in January, 2007, at what was billed as an "organizational meeting" of the party, Orman and Korchin appeared, each claiming to be the party chairman. Korchin announced the annual party meeting would be held in August and left, after which the Milford gathering elected Orman as chair, by a 5-1 margin.
On July 10, 2007, Orman wrote to Bysiewicz and Jeffrey Garfield, executive director of the Elections Enforcement Commission. He asked them to have the state attorney general's office investigate the petitioning done by Lieberman in 2006. Orman's contention was that Lieberman had violated state law by knowingly circulating false petitions, in that he had no actual intent to join or form a new party.
The next month, Korchin told the Hartford Advocate that he had held another party meeting on August 9, although he refused to say where it had occurred. Orman said he had not been informed of any such meeting. Korchin responded that Orman had been notified but had "declined to attend in an e-mail.
On March 6, 2008, there was a statewide party caucus organized by the faction that had chosen Orman as party chair. With Orman declining to run for re-election, John Mertens was elected to succeed him.
Lieberman himself is not a member of the party; he is a registered Democrat. The Senate website lists him as an Independent Democrat.
The two competing factions have differing views of the party's mission in the wake of the 2006 election.
As Orman expressed it in 2007, "What we said was that if the state was going to allow a fake institution to exist, we were going to turn that fake institution into a real party to hold Joe accountable."
Korchin, however, stated: "Connecticut for Lieberman is a new political party that carries on what used to be the ideals of the Democratic Party: A liberal approach to domestic issues coupled with a strong commitment to a robust foreign policy. New members who subscribe to this platform are welcome."
