Incumbent Democratic U.S. Rep. Colleen Hanabusa raised $224,000 in the first quarter of 2012 as she prepares for an expected rematch with Republican Charles Djou for the seat they competed for two years ago.

Quarterly reports are due to the Federal Election Commission by today.

Hanabusa’s take for the January-March period brings her total for the election cycle to $770,000, and she has about $428,000 in cash on hand, according to her campaign.

Djou’s quarterly numbers were not available.

Neither is expected to spend much 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.
