With shadowy nonprofit groups expected to spend millions this year to influence Arizona voters without disclosing the sources of their money, both candidates for the state office overseeing elections are offering plans to address the practice.

A bill aimed at requiring more disclosure of the anonymous and unlimited campaign funds known as “dark money” received a unanimous vote but not exactly a vote of confidence from a Senate committee.

The attempt to repeal last year’s big election law has taken up much of the spotlight so far this session, but it’s far from the only election issue lawmakers are tackling before they hit the campaign trail this year.

Lawmakers attempted to push through a set of bogged-down election bills in a comprehensive 43-page amendment in conference committee Wednesday afternoon, but the committee was called off minutes after the amendment began circulating at the Capitol.

The debate over whether to raise Arizona’s traditional campaign contribution limits may ultimately end up in court, but enough state senators ere convinced Tuesday that adjusting contribution limits for individuals and political action committees does not require a three-quarter vote.

For all of the controversy during the last election over the influence of so-called dark money in politics, the Arizona State Legislature is unlikely to produce any laws on the subject this session.

Supporters of former Senate President Russell Pearce weren’t able to stop his foes from putting him on a recall ballot in 2011.

But stopping the next recall effort may be a lot easier.

Hoping to lessen the crush of provisional ballots that delayed the final tally after the November election, the new Senate Elections Committee took its first step in changing the laws governing Arizona’s Permanent Early Voter List.

The large number of provisional ballots cast in November has two lawmakers so far proposing ways to address the issue. Rep. Chad Campbell, D-Phoenix, the House minority leader, said he is drafting legislation to form a committee to study election problems and recommend legislation.
