A member of the Federal Election Commission says it is time to fix the broken public financing system for presidential candidates.

Ann Ravel, one of the commission's most outspoken members, wants the commission to recommend legislation to Congress that would dramatically change the system financed by a voluntary check-off on individual tax returns.

In a memo released Friday, Ravel asked the commission to take up the subject at its Sept. 29 public meeting.

She recommends removing the spending limits that have kept mainstream candidates from applying for federal money. She also recommends that the law make it harder for candidates to qualify.

Ravel wants to raise the federal match for qualifying candidates.

The fund, which was set up as a Watergate-era reform, has $315 million sitting idle because mainstream candidates do not want to limit their spending and fundraising, as the law requires.

Green Party candidate Jill Stein is the only 2016 candidate still receiving money from the fund.
