Candidates running in a closely watched Democratic primary race for the U.S. Senate checked their tone in a forum on Hawaii's Big Island.
U.S. Sen. Brian Schatz said Wednesday night that he will not go negative in the campaign. But U.S. Rep. Colleen Hanabusa came across as ready to fight.
Hanabusa says the truest test of one's skills comes when they are in the minority, and she serves in the minority in the U.S. House.
She says it should be easier to make changes in the Senate, where Democrats are in the majority.
Schatz says his record on protecting Social Security is better than Hanabusa's. He points to her 2013 vote on an amendment that undermined Social Security benefits.
Hanabusa says bills get changed over time.
