Former Republican U.S. Rep. Charles Djou’s campaign reported raising $84,000 in the first quarter of 2012 as he prepares for an expected rematch with incumbent Democratic U.S. Rep. Colleen Hanabusa in the November general election.

Djou, who returned in early March from a six-month deployment in Afghanistan with his U.S. Army Reserve unit, has raised about $256,000 in the current election cycle, according to his report filed this week with the Federal Election Commission.

Including money carried over from his 2010 campaign, Djou has about $387,000 in cash on hand.

Hanabusa reported raised $224,000 in the first quarter of 2012, for a total of $770,000 with about $428,000 in cash on hand.

Neither is expected to spend heavily before the Aug. 11 primary — each is favored to win their party’s nomination to represent the 1st Congressional District, representing urban Oahu. It would be a rematch of 2010, when Djou was the incumbent after winning a special election in May of that year to fill the final months of the term vacated by Neil Abercrombie, who had resigned to concentrate on his run for governor.
