— Hawaii rushed to clean up debris from one tropical storm with only a day to prepare for the next hurricane on its way, but aimed to squeeze in a primary election vote on Saturday.

Voters are to decide a Democratic primary contest between Gov. Neil Abercrombie, who has a thriving economy on his side, and state Sen. David Ige, who has surged to a double-digit edge in polls despite raising less campaign cash.

All but two polling stations on the east coast of the Big Island, hardest hit by Tropical Storm Iselle, will be open, election officials said. Iselle weakened from a hurricane before it struck the Big Island on Thursday, and lost more force as it later pushed past the U.S. state.

“I think we’ve come through in great fashion,” Abercrombie told an evening news conference, a nod to the fact that the storm did much less damage than had been feared.

As thousands of residents scrambled to clean up fallen trees that downed power lines, officials warned against complacency given the extent of the disruption and the uncertainty over the pathway of the bigger storm hurtling toward them.

Hurricane Julio, which was downgraded to a Category 2 storm on Friday, was packing maximum winds of 100 mph as it churned about 500 miles off the Big Island city of Hilo and 685 miles east of the state capital, Honolulu, the National Weather Service said Saturday morning.

Forecasts showed Julio likely tracking about 150 miles north of the archipelago early on Sunday at the earliest, meteorologists said. “Gradual weakening is forecast during the next couple of days, but Julio is forecast to remain a hurricane through Sunday night,” said a Weather Service advisory.

There were no reports of major injuries from Iselle, a boon to a state economy that depends heavily on tourism. About 95,000 tourists were visiting Oahu, the state’s most populous island, when Iselle hit.

The American Red Cross said Friday that 900 people remained in evacuation shelters and a utility company said an estimated 15,000 customers on the Big Island have spent two nights without power.

“The air is thick with wood smoke since the power is still out,” said Malia Baron, who was visiting the volcano area of the Big Island. “It’s been quite the adventure, but we’re ready to head home to prep for the next storm.”

The storm was responsible for a rare lull in campaigning.

As the election loomed, the U.S. Coast Guard said it had reopened all of its ports in the state except one on Molokai, which would be evaluated early on Saturday, and farmers on the largely rural Big Island were checking crops such as fruit and macadamia nut trees for damage.

Election analysts said it was unusual for an incumbent governor to struggle given the strength of the economy, with unemployment near a record low, tourism going well and state coffers sound.

Hawaii has consistently reelected Democratic governors since Republican Bill Quinn was ousted in 1962. A late July poll of 458 likely voters conducted for the Honolulu Star-Advertiser puts Ige 18 points ahead Abercrombie at 54-36 in the primary contest.

Abercrombie told supporters in a statement that Hawaii polls historically have often failed to presage actual results.

Supporters say Abercrombie has achieved much, signing gay marriage legislation into law, helping to negotiate a North Shore land conservation deal and championing development in downtown Honolulu. He also represented Hawaii in the U.S. House of Representatives from 1990 to 2010.

Ige’s campaign issued e-mails urging voters to cast ballots early because of the storms. The winner will face Independent and Republican candidates in November’s general election.
