A decade ago, it seemed Albuquerque’s new public financing program had proven itself. All three mayoral candidates in 2009 used public money to run their campaigns, keeping expenditures under $400,000 each, well below the almost $1.2 million the incumbent mayor had spent in 2005 to get re-elected. Public financing freed candidates to talk to voters rather than spend all their time fundraising, supporters said, while making it possible for them to compete against candidates raising money from big donors. They also hoped reducing the amount of money spent might inspire more confidence in the political process. Then a 2011 U.S. Supreme Court decision in an Arizona case invalidated a provision in Albuquerque’s law that provided additional funds when expenditures by private competitors exceeded the initial city disbursements to publicly funded candidates.
