WASHINGTON — Sen. Daniel Akaka, a Hawai`i superdelegate, announced today that he is endorsing Barack Obama for president with the hope the Illinois senator will end the "partisan politics that has plagued our country far too long."

"I've followed the campaign for president closely … to see which candidate would articulate a vision for our country, encourage hope and renew faith in our government, and stand to rigors of a nationwide contest," Akaka said in a statement released by Obama's campaign office. "I've decided that for me, that candidate is Barack Obama."

Akaka was the last uncommitted superdelegate in Hawai`i's congressional delegation.

On Friday, Rep. Mazie Hirono, D-Hawai`i, endorsed Obama, who was born in Hawai'i and attended Punahou School.

Akaka said that Obama's Hawai`i background made him uniquely qualified for a presidential candidate.

"I have great hope that in his own way, Barack Obama will achieve what I have been working to accomplish my entire congressional career - more tolerance and understanding, an appreciation for common goals and interests, rather than an emphasis on our differences," Akaka said.

In making his endorsement, Akaka said he held Hillary Rodham Clinton and Bill Clinton "in the highest regard as colleagues and friends."

"Sen. Clinton has campaigned hard and well and I wish her all the best as we move forward," Akaka said.
