PAHOA, Hawaii (AP) -- Incumbent U.S. Sen. Brian Schatz won a tense Democratic primary election in Hawaii, proving that he is no longer just a senator who was appointed to his seat - he has captured the confidence of Hawaii voters.The dramatic race to finish the term of the late Sen. Daniel Inouye was tinged with emotional residue from the past. Schatz was challenged by U.S. Rep. Colleen Hanabusa, who at one point said that he wasn't a true incumbent because he had been appointed by Gov. Neil Abercrombie after Inouye's dying wish that Hanabusa replace him.Now, after an election that stretched over nearly a week because Tropical Storm Iselle knocked out power and closed polling stations, Schatz has carried his slim election-night lead to a victory.\This was obviously an extremely hard-fought race. But we're gratified that the voters heard our message and recognized that I've been working hard for the people of Hawaii
