The National Republican Congressional Committee is jumping into one of Arizona’s most competitive races with $900,000 in airtime in the 9th Congressional District.

Johnnie Robinson has won the Democratic nomination for the 4th Congressional District seat.

Robinson and Mikel Weisser had been separated by less than one-tenth of a percentage point following last month’s primary election. Robinson was declared the winner this week after a recount of votes.

The battle between Democrat Kyrsten Sinema and Republican Vernon Parker over Arizona’s new 9th Congressional District will be close. That’s about where most predictions begin and end.

Democrat Kyrsten Sinema holds a narrow lead over Republican Vernon Parker in Arizona’s 9th Congressional District, according to a poll commissioned by Sinema supporters.



But after testing a slew of negative messages against both candidates, Sinema’s lead widened to double digits.

As Vernon Parker seeks to clear his name in allegations that led to his company’s termination from a federal program, his Democratic rival for Arizona’s 9th Congressional District is bringing back an issue that hounded him in his last run for Congress.

Since Kyrsten Sinema first began eying a run for Congress, a question loomed over her candidacy — could someone whose own party once called her too extreme win in a moderate district?

In a showcase of post-primary unity, Kyrsten Sinema announced the endorsements of two high-profile supporters of her opponents in the Democratic primary for Arizona’s 9th Congressional District.

The Democratic Congressional Campaign Committee stepped up the attack on Republican Jonathan Paton this week and has so far committed half a million dollars in TV advertising to help former U.S. Rep. Ann Kirkpatrick in her bid to win the seat.

The Democratic primary in Arizona’s 9th Congressional District was one of the most high-profile races in the state, but it was Republicans who turned out en masse to cast their ballots.

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