Acting Mayor Kirk Caldwell is winning the fundraising race in the Honolulu mayoral election, according to campaign finance reports filed with the state Monday.

Caldwell received $303,252 in contributions from Jan. 1 to June 30, almost 50 percent more than brought in by former Honolulu City Prosecutor Peter Carlisle, who raised $214,619. The two are vying to complete the final two years of former Mayor Mufi Hannemann‘s second term. Hannemann resigned last month to run for governor. University of Hawaii engineering professor Panos Prevedouros was a distant third, raising $30,098. City Councilman Rod Tam trailed with contributions of $5,715.

Caldwell and Carlisle were separated by less than $50,000 when it came to cash on hand at the end of June, with Prevedouros again in a different league. Both Caldwell and Carlisle support the proposed Honolulu rail project. Prevedouros opposes the project.

Monday was the deadline for candidates in local races to turn in their first campaign finance report of the year. Called a 1st preliminary primary report, the filing is a financial update that shows how much each contender has raised and spent from Jan. 1 to June 30. The reports provide a good look at who, as of this summer, is leading in the money race.

The mayoral election will be held on the Sept. 18 primary date, with the winner of the most votes taking the office. There will be no runoff.
