Martha McSally scored the political redo of a lifetime when she was appointed to the U.S. Senate on December 18.

Two-time U.S. Senate candidate Kelli Ward said Monday she'll seek the top post in the Arizona Republican Party and likely forego any effort to seek the late Sen. John McCain's seat in 2020.

The winner of Arizona’s Democratic gubernatorial primary — whoever it is — will likely be strapped for cash upon entering the general election.

May 30 marked the deadline for candidates to submit petitions to run for legislative, statewide and congressional offices. Unlike in previous election cycles, few legislative races are uncontested.

Arizona Republican Congresswoman Martha McSally called on the national GOP to "grow a pair of ovaries" as she launched her bid for the U.S. Senate on Friday, joining the race to replace retiring GOP Sen. Jeff Flake by embracing President Donald Trump and his outsider playbook in one of the nation's premier Senate contests.

Donald Trump remains more popular in Arizona than the nation as a whole. But pollster Mike Noble said it doesn't look like that will help the Republican Party hang on to the Senate seat being vacated by Jeff Flake.

U.S. Rep. Martha McSally, Congressional District 2, has told Republican colleagues that she will enter the race for the U.S. Senate seat being vacated by fellow Republican Jeff Flake, a move that puts a mainstream candidate who could win backing from President Donald Trump into the primary race.

U.S. Sen. Jeff Flake today announced that he isn’t running for re-election. The news, which the Arizona Republic broke, is expected to upend the state’s political scene and could plunge the Arizona Republican Party into disarray.

Arizona Republican Sen. Jeff Flake’s re-election race is becoming a case study in the GOP’s convulsions among the establishment, a furious base and angry donors.

Republican Jay Heiler, a regent and the founder of charter school operation Great Hearts Academies, is considering a run for U.S. Senate against Republican incumbent Jeff Flake.
