Schatz and Hanabusa each garner the support of 37 percent of voters in the poll of likely Democratic primary voters conducted by The Mellman Group.
Those results differ from those in a recent survey for EMILY's List, a group that supports female pro-abortion-rights Democrats and has endorsed Hanabusa. She holds an 11-point lead in that poll of likely Democratic primary voters, which was conducted in early June by Clarity Campaigns.
The senator was appointed after Sen. Daniel Inouye's (D-Hawaii) death to fill the remainder of his term. According to his poll, he isn't as well known as Hanabusa, whom Inouye requested be named to his seat, but is better liked by those who know them both. He leads by 13 points with Democratic voters familiar with both candidates in his own poll.
Schatz's poll of 600 likely Democratic primary voters was conducted from June 26-30 and has a margin of error of 4 percentage points. The EMILY's List poll of 771 likely Democratic primary voters was conducted from June 10-11 and has a margin of error of 3.53 percentage points.
