A public-opinion poll released today says both Neil Abercrombie and fellow Democrat Mufi Hannemann would handily defeat Republican James “Duke” Aiona in the Hawaii governor’s race.

The results come from a June 24 telephone survey of 500 likely Hawaii voters conducted by Rasmussen Reports, an electronic media company specializing in polling.

Abercrombie leads Aiona 58-32 percent, with 3 percent undecided and 6 percent preferring another candidate.

Hannemann leads Aiona 52-30 percent, with 9 percent undecided and 9 percent favoring another candidate.

The results are essentially unchanged from a Rasmussen survey in March. The margin of sampling error is +/-4.5 percentage points, with a 95 percent level of confidence.

Abercrombie, a former Congressman, and Hannemann, mayor of Honolulu, would also easily defeat another Republican, John Carroll.

Both parties pick gubernatorial candidates in the Sept. 18 primary.

Other poll results:

• Opinions on Abercrombie include a 32 percent “very favorable” and a 22 percent “very unfavorable” rating.

• Opinions on Hannemann are 25 percent very favorable and 16 percent very unfavorable.

• Opinions of Aiona are 22 percent very favorable and 21 percent very unfavorable.

• Sen. Daniel K. Inouye has a more than 3-to-1 lead over his only announced Republican opponent.

• 43 percent of Hawaii voters favor repealing the national health-care bill.

• 37 percent support a tough immigration law like Arizona’s; 52 percent support a police check of immigration status.

• For term-limited Gov. Linda Lingle, 47 percent approve of her performance while 51 percent disapprove — also essentially unchanged since the March poll.

It’s time to join the discussion on the governor’s race.
