What can California ballot measure committees spend money on?  The California Democratic Party has filed a complaint alleging that such a committee improperly paid for ads featuring Gov. Arnold Schwarzenegger, according to this story.

Roman Porter, executive director of the FPPC, declined to comment on the governor’s case, but said regulations adopted by the commission are meant to make sure candidates are not using the ballot measure committee’s they control to promote themselves.

“The regulation was intended to provide greater transparency to the media and public about the number of committees controlled by office holders and to ensure that money raised without limits is spent only on ballot measures or potential measures, not on candidate activities,” Porter said.
