With more than a year until the election, congressional candidates in Arizona have already spent $5.5 million on their campaigns – for everything from consultants to coffee mugs, according to the latest Federal Election Commission filings.

After a razor-thin loss last year to Democrat Ron Barber in southeastern Arizona's 2nd Congressional District, Republican Martha McSally is beginning the 2014 race with a significant amount of money in the bank.

Gabrielle Giffords may not be running for Congress, but she’s putting the money from her campaign to use. Her campaign contributed $202,500 to the state Democratic Party’s federal campaign committee.

The contributions through the end of May came during the hotly contested special election for her vacated seat in the 8th Congressional District, a race that saw Democrat Ron Barber, Giffords’ former district office director, defeat Republican Jesse Kelly.

After just four days, Ron Barber has raised more money and attracted more contributors than some campaigns have gotten in months.

Through the online Democratic fundraising PAC ActBlue, Barber raised about $110,000 from 1,715 contributors through Monday morning, according to his campaign.
