Just six months after Tucson Congressmen Ron Barber and Raúl Grijalva were sworn in to new terms, candidates are already lining up to run against them in November 2014.
On Monday, Republican Martha McSally filed paperwork to make her candidacy official, but a quarterly campaign-finance report shows she's been fundraising all year.
This will be her third run for a House seat. The retired Air Force colonel lost to Barber by less than 1 percent last year.
Barber had $327,873 cash on hand at the end of March and raised twice as much money as McSally in 2012.
Gabriela Saucedo Mercer will try again to oust six-term Congressman Grijalva. In 2012 she received 38 percent of the votes, and he won 58 percent.
The Republican activist filed her candidate paperwork on March 25.
She will be challenged again in the Republican primary election by businessman Jaime Vasquez.
Congresswoman Ann Kirkpatrick has no official challenger yet, and she had $245,000 cash on hand at the end of March.
