AZ-Sen, AZ-09: On Friday, local NBC-affiliate KPNX reported that Democratic Rep. Kyrsten Sinema is planning on running for Senate against Republican incumbent Jeff Flake, while Phoenix Mayor Greg Stanton, a fellow Democrat who has reportedly been considering a Senate bid of his own, will instead run to replace Sinema in the House. Neither Sinema nor Stanton has formally declared yet, and Sinema responded only by issuing a statement that she is seriously considering running, but thats still the most direct she has been about her interest in the race.
Sinema would be a top recruit for Democrats in this light-red state, where the party has a relatively thin bench of prominent elected officials for a statewide race, and she has long been seen as one of the likelier potential Democratic contestants against Flake. Sinemas has already been fundraising like someone thinking about running for Senate, having brought in $633,000 in the second quarter and finishing the month of June with $3.2 million in the bank, which was even more than Flakes $3 million in cash-on-hand. This hefty fundraising comes even as Sinema won her last race by 61-39 and doesnt appear vulnerable if she were to seek re-election in 2018.
If Sinema does end up running, it may be because Flake has eviscerated his public standing in the Grand Canyon State by pissing off both swing voters and the far-right element of the party base that has long viewed him with skepticism. As one of the Senates relatively hardcore libertarians on fiscal issues, Flake voted for all of the GOPs recent health care bills, which have been extremely unpopular and would prove especially harmful to states like Arizona that expanded Medicaid. Indeed, one recent PPP poll found Flakes approval rating at an atrocious 18 percent with 62 percent disapproving, and it showed him losing to a generic Democratic candidate by 47-31.
On the other hand, Flakes vocal opposition to Trump has landed him in hot water with the party base, which still adores Trump in Arizona. This hostility to the partys current leader culminated with Flake secretly writing a book where he lambasted the party for making a deal with the devil and abandoning the movement-conservative principles of those like former Arizona Sen. Barry Goldwater in order to win power with someone unorthodox like Trump. Flake is notably far less hawkish on immigration than Trump, but Arizona Republicans are notorious for favoring harsh anti-immigrant laws. Consequently, that same PPP poll placed Flakes approval at just 22 percent with 57 disapproving among Republicans.
Flakes visible apostasies have incurred the ire of many prominent hardliners in the GOP, and he currently faces a primary challenge from former state Sen. Kelli Ward, but Ward has her own flaws and raised just $183,000 in the second quarter. However, she held longtime Sen. John McCain to just a 51-40 win in the 2016 primary, and Flake is much less entrenched than McCain was. Previous reports indicated that Trump himself is keen on finding a challenger to Flake, but some Republicans werent sold on Ward. However, billionaire GOP mega-donor Robert Mercer recently dropped $300,000 on a super PAC to support Ward in the primary. The Mercer family spent $700,000 supporting Wards 2016 campaign, and their influence with other major donors could open up the doors for even more money.
Theres still about a year to go until Arizonas 2018 primary, and Flakes numbers could record somewhat as more time passes since the health care debate. However, he Flake could emerge damaged even if he ultimately wins renomination, and Democrats are certain to attack him over Trumpcare. Sinemas three-term congressional career has shown her demonstrate remarkable political caution, having evolved from a Green Party-supporter in the 2000 presidential race to maintaining a centrist congressional voting record in likely preparation for an eventual statewide campaign in this Republican-leaning state. Her potential candidacy is a sign that Flake is indeed vulnerable to defeat in what is shaping up to be a Democratic-favoring year nationally.
If Sinema does take the plunge, she would leave behind a suburban Phoenix and Tempe-based 9th District that swung from a narrow 51-47 Obama edge to a wide 55-38 Clinton victory. Having served as mayor of Arizonas largest city since his initial 2011 election, Greg Stanton would be a strong contender for Democrats and would likely be favored to hold this seat for Team Blue if he ends up running to replace Sinema.
