Kirk Caldwell reported raising $603,000 in the 10 weeks since the primary election, bringing his total for the campaign at about $1.5 million, according to his campaign.

The $1.5 million surpasses the $1.2 million he raised in his failed 2010 campaign.

In a news release tonight, the campaign reported $75,000 in cash on hand. Caldwell’s campaign released the preliminary numbers in advance of posting the final report online.

Former Gov. Ben Cayetano, Caldwell’s mayoral rival, reported raising $339,000 in the same period, bringing his total for the campaign to $1.3 million.

Spending reports for the period from Aug. 12 to Oct 22 are due by midnight to the state Campaign Spending Commission. 

“The numbers are indicative of the solid momentum and grassroots support since the primary election and I extend my heartfelt gratitude to all of our supporters,” Caldwell, former city managing director, said in a news release. “We have reached out to every community on Oahu addressing all the issues and concerns that our citizens have.”

Cayetano’s report was filed this evening. There was no immediate comment from his campaign.

Caldwell still carries a campaign debt of $218,000, most of that left over from 2010. Cayetano’s listed a campaign debt of $50,000.

The new numbers mark the first time Caldwell has overtaken Cayetano in fundraising in the race.

Caldwell also overtook Cayetano in the recent Hawaii Poll. According to the poll, Caldwell leads 53 percent to 42 percent, with 5 percent undecided.
