The state would defend its new campaign finance law in court if necessary, a spokesman for Gov, Jan Brewer says.
Spokesman Matt Benson said Friday that Brewer signed the measure that significantly increases campaign finance limits because candidates have become bystanders in their own elections.
Brewer signed into law late Thursday the bill allowing state, legislative and other candidates to raise thousands of dollars more each election.
The Arizona Republic reported that the measure increases the limit for legislative candidates from $488 through the primary and general elections to nearly $2,500 from individual donors and $5,000 from some political committees.
The law allows candidates to collect the maximum contribution twice — during the primary and the general election.
Benson said Brewer is worried about the Citizens United court ruling that paved the way for a flood of campaign cash from corporations, unions and wealthy interests. That ruling by the U.S. Supreme Court said, in essence, that free speech rights were limited by campaign finance ceilings.
It led in last year's presidential and congressional elections to billions of dollars of spending by individuals and organizations outside the bounds and controls of the candidates and their campaigns.
Arizona Democrats oppose the lifting of limits because it could make it difficult for any candidate to successfully run under Clean Elections, the state's public campaign financing system created by voters in 1998.
