Democratic U.S. Rep. Kyrsten Sinema announced today that she is running for the U.S. Senate, ending months of speculation on whether she would challenge U.S. Sen. Jeff Flake for the seat.

New reports filed with the Federal Election Commission show Brewer was able to get nearly $42,000 in donations in the last half of 2013 to Jan PAC. That brings her annual collections up to more than $272,000.

Democrat Felecia Rotellini, who narrowly lost the attorney general’s race in 2010, is coming back for another run at the job, setting up a potential rematch with Tom Horne.

Democrat Richard Carmona bought $139,200 worth of ads on Spanish-language television stations against $89,200 by Republican Jeff Flake during their tightly contested U.S. Senate race, according to documents kept by the outlets.

Jeff Flake entered the race more than a year and a half ago as Arizona’s U.S. senator in waiting, only to end up facing the Democrats’ toughest candidate in a quarter century. But the Democrats’ best play for an Arizona Senate seat since 1988 wasn’t enough to keep the six-term congressman down.
