Among Hawaii’s four so-called Super PACs, one didn’t attract any money over the second half of 2011, another raised $561 strictly from donations of less than $100.

The other two have yet to file a report, according to the latest round of campaign finance reports. The reports were due by midnight Tuesday.

Super PACs, officially called “independent-expenditure-only” committees, can raise and spend unlimited amounts of campaign money from corporations, unions and individuals. They money can be used to support or attack candidates through advertising, mailings and other means so long as they operate independently of those campaigns.

Kauai Women’s Caucus reported raising zero funds for the six-month period. Hawaii Solutions reported the $561 in donations. Contributors who give less than $100 over an election cycle do not need to be named.

Automated HealthCare Solutions had not filed a report as of noon Wednesday. Neither had MADPAC Hawaii. (MAD stands for “Make a Difference,” according to the PAC’s site.)
