Former Arizona State University quarterback Andrew Walter formed a campaign committee for a run in Arizona’s 9th Congressional District, giving first-term Democratic Congresswoman Kyrsten Sinema a potential Republican challenger with a built-in base of support among the Sun Devil faithful.

Arizona's U.S. House delegation split along party lines late Tuesday night as the House passed the so-called "fiscal cliff" agreement.

Arizona’s new hypercompetitive 9th Congressional District lived up its billing, with Democratic nominee Kyrsten Sinema holding a narrow but growing lead over Republican Vernon Parker in a race that was still undecided at the end of election night. As of Wednesday evening, Sinema, a former legislator from central Phoenix, leads by 2,715 votes.

Seven hundred thousand dollars wasn’t enough to win the race that would have been the Club for Growth’s signature victory in Arizona.

Congressman David Schweikert took an early lead in his battle with fellow incumbent Congressman Ben Quayle.

Schweikert had about 54 percent of the vote in Arizona’s 6th Congressional District, according to early ballot results from Maricopa County. Quayle trailed with 46 percent.

Arizona's primary election Tuesday features a spirited race for the Republican nomination for U.S. Senate and heated contests for several U.S. House seats, with outcomes that will set the roster of candidates for the Nov. 6 general election.

Primary season has already done what hurricane season is only threatening to do: Driven some party members away from next week’s Republican National Convention in Tampa, Fla.
