Arizona Rep. David Schweikert is preparing to take on fellow Republican Rep. Ben Quayle in a primary fight, even as Quayle struggles to decide in which district to run.

Republicans from the West Valley on Wednesday nominated a district party chairwoman and two others to replace the House seat formerly held by Sen. Judy Burges.

Congressman David Schweikert has endorsed his former colleague Matt Salmon in the race to replace U.S. Rep. Jeff Flake.

Congressman Jeff Flake continued his fundraising dominance in the U.S. Senate race, reporting $607,000 raised in the fourth quarter of 2011.

Don Bivens reported bringing in $390,000 for his U.S. Senate campaign in the fourth quarter of 2011, including $160,000 of his own money.

Tucson state Rep. Matt Heinz is the first Democrat to formally enter the special election race to replace U.S. Rep. Gabrielle Giffords, who resigned Jan. 25 to focus on her recovery from an assassination attempt more than a year ago.

Former U.S. Senate hopeful David Crowe has officially switched races and will challenge U.S. Rep. Raul Grijalva in the Democratic primary.

Crowe, a Tucson defense contractor, filed a statement of candidacy with the Federal Election Commission on Jan. 12, according to FEC records. The same day, he told the Arizona Capitol Times that he wasn’t yet sure whether he would run against Grijalva in the new 3rd Congressional District or run for the seat recently vacated by U.S. Rep. Gabrielle Giffords.

Andrei Cherny, chairman of the Arizona Democratic Party, is stepping down from his position in order to take on a “new and different task.”

He didn’t mention it in the letter he sent out today, but Cherny is expected to soon announce he is running for Congress in the new 9th Congressional District, which includes parts of Phoenix, Scottsdale, Tempe, and Mesa.

Former Congressman Matt Salmon raised $152,514 during the last quarter of 2011, bringing his total haul to $470,439 for the year.

In the wake of two of Arizona’s biggest political shake-ups of last year, lawmakers are hoping a little sunshine will help clean up the mess.

Shadowy groups involved in the recall of then-Senate President Russell Pearce brought to light some of the flaws in the current financial disclosure requirements. Meanwhile, the Fiesta Bowl scandal brought to light ethical questions about what should be considered a gift from a lobbyist.
