The GOP has two fewer representatives in the New Hampshire House.
A Republican legislator from Sandown is leaving the party, saying Gov. Craig Benson doesn't care about state residents, and that Republicans are cheering Benson on.
Corey Corbin said Benson, through his budget plans, is assaulting kids, senior citizens, small businesses and working families.
"The corner office has become the place jokes are made of," Corbin said. "I don't believe there is anyone who takes this man seriously."
A message was left seeking comment Thursday afternoon for Kelly Ayotte, a Benson spokeswoman. New Hampshire Republican Committee spokeswoman Julie Teer had no comment on Corbin's decision.
Democratic Chairwoman Kathy Sullivan welcomed Corbin into the party.
Also, Republican Rep. Donald Stritch of Auburn resigned from the Legislature, effective immediately. Stritch was elected a commissioner of Rockingham County on Wednesday. His district will hold a special election to fill his House seat.
Corbin said he did not take the decision to become a Democrat lightly. "It is an emotional decision, as I have been a loyal member of the GOP since my high school days," he said Wednesday. "However, when a party so abandons the best interests of our working families, like the GOP has in New Hampshire, loyalty can play only a very small role in making the decision to do what's best for those I represent."
He said he is interested in running for the state Senate.
