Republican candidate for governor Mark Fisher is suing the head of his party to get his name on the September primary ballot.

Fisher's campaign said the lawsuit was filed Tuesday in Suffolk Superior Court against MassGOP chairwoman Kirsten Hughes.

Party officials said Fisher, a tea party member, received 14.765 percent of the delegate vote, just shy of the 15 percent required. The party counted blank votes toward the total.

Fisher argued `blank' ballots should not be counted. He said that would have put him just over 15 percent.

Party officials declined comment Tuesday.

Charlie Baker, who easily won the party's endorsement for governor, said he respects Fisher's decision and he's confident the party will work to ensure the process was fair.

Baker said if it's determined a primary is needed, he'll welcome it. (Associated Press)
