Island with a state capital (4)

I believe the answer is:

oahu

'island with a state capital' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for oahu that I've seen before include "Hawaiian island" , "Chief island of Hawaii" , "Pacific island" , "popular Pacific location" , "Honolulu's island" .)

I've seen this clue in the Universal, the Newsday, the USA Today, the New York Times, the Wall Street Journal, the LA Times and the Newsday.com.
