Mayor Mufi Hannemann took 88 percent of the voting precincts in Tuesday's general election, capturing 188 of the 212 polling locations on O'ahu.

After failing to capture more than 50 percent of the vote in the Sept. 20 primary election, Hannemann rolled to victory in Tuesday's runoff, beating City Councilwoman Ann Kobayashi by more than 47,000 votes. Hannemann took 58 percent of the vote, Kobayashi 42 percent.

Hannemann also captured 90 percent of the absentee voting segments.

Precinct-by-precinct vote tallies released yesterday show that Hannemann did well across the island, and that his margins were greatest in Central and West O'ahu.

He captured more than 70 percent of the vote at three precincts in the Kapolei and Waikele area and regularly captured more than 60 percent of the vote at precincts up and down the Leeward Coast.

Of the 24 precincts won by Kobayashi, most were clustered in East Honolulu, in portions of Kobayashi's Makiki-Kapahulu council district, on the North Shore and on the Windward side, according to data released by the state Office of Elections.

An increase in voter turnout — 66 percent compared to 37 percent in the primary — benefited the incumbent Hannemann, according to Neal Milner, a political scientist and the ombudsman at the University of Hawai'i.

Following the primary election, Hannemann said he needed to do more to get out the vote, especially in West O'ahu.

Hannemann won by a larger margin than did the rail-transit question, a possible indicator of his success at making the election more than a referendum on a single issue.

"He certainly accomplished what he said was the problem the first time. He got out the vote and increased support in West O'ahu but I think he had pretty strong support all along the line," Milner said. "His support was weakest (in East Honolulu) ... but he still did pretty well there. He was strong in all areas."

Milner lauded Hannemann's efforts to embrace the campaign of Barack Obama as another successful strategy. Obama took 69 percent of the O'ahu vote, to McCain's 28 percent.

Hannemann campaign officials said they were pleased with the precinct data released yesterday.

"These results show that there were many people who voted for Mufi Hannemann, even though they may not have supported rail," said campaign spokesman A.J. Halagao. "The voters clearly understand that Mayor Hannemann is more than a one-issue candidate; rather, he is an experienced, proven leader they can trust to lead our island and move us in the right direction."

The Kobayashi campaign was hampered by its July 22 late start and a nearly 10-to-1 fundraising disadvantage. Hannemann spent more than $1 million from Jan. 1 to Oct. 20.

"We worked very hard with the volunteers who turned out for our grassroots effort. We canvassed as much as we could and tried to time and maximize our advertising buys," said City Councilman Donovan Dela Cruz, Kobayashi's campaign chairman. "Despite all of that, it was a valiant effort and decent showing."
