Polls closed in Arizona on Tuesday, where Republicans on Tuesday will decide a three-way battle over which candidate to nominate to replace the state's junior U.S. Senator, who is retiring because he has no political future after criticizing President Trump.
Both Ward and Arpaio have stoked plenty of controversy in the past, and that has Republicans anxious about their hold on the seat if either becomes the nominee.
Barb Ruguone, 78, cast her ballot Tuesday for McSally at a Phoenix library. "It seems like she wouldn't be intimidated", Ruguone said. The CBS poll showed Sinema beating McSally, 41 percent to 34 percent. If a majority of voters chooses one of the most conservative candidates, that could encourage him to choose a candidate who is more of a hard-liner on the issues Trump cares about most deeply, especially immigration.
U.S. Rep. Martha McSally, a two-term congresswoman from Tucson, defeated her Republican rivals, former state Sen. Both nominees have pledged not to campaign then or Thursday in his honor.
In a statement acknowledging her primary win, Sinema made no mention of her opponent. "It's up to all of us to follow his lead of always putting country over party", the Democrat said. "It's hard to celebrate anything this week", she said.
Dr Tipirneni brings a data-driven, policy solution approach to the campaign, she said, which would attract independent voters. "Between a patriot and a protester". In the state's 9th Congressional District, Steve Ferrara, the former Navy chief medical officer, won the GOP nomination to face Greg Stanton, Phoenix's Democratic former mayor.
The seat is considered a key pickup for Democrats in their bid to take control of the chamber, meaning the general election will be among the closest-watched races in the nation between now and November.
Though the general election is still months away, McSally has already blasted Sinema in a TV ad for "protesting us in a pink tutu" rather than serving in the military after 9/11.
After yesterday's primaries, only five states remain to pick candidates before full attention turns to the November election, when all 435 House seats, 35 Senate seats and 36 governors' offices will be at stake. But his more moderate stance on immigration and his deciding vote past year against Trump's efforts to repeal President Barack Obama's health care law turned off many GOP voters. In mid-August, McSally's campaign boasted about the president calling her "terrific" while introducing her at an event.
Ms. McSally had more than 50 percent of the vote in early returns, easily outdistancing former state lawmaker Kelli Ward and former Maricopa County Sheriff Joe Arpaio, whose second loss in as many elections likely ends his political career.
The Republican primary, however, featured three significant and well-known candidates. McSally drew criticism from McCain's family when she did not mention his name in the signing of the recent defense bill, which was named after McCain. After his family announced McCain was ending medical treatment last week, Ward speculated in a deleted Facebook post that the move was created to hurt her campaign.
On Monday, Ward tweeted, "Political correctness is like a cancer!"
A Democratic victory in the Senate race could suggest the state could be up for grabs in 2020.
The Republican victor will face whoever emerges from a crowded Democratic gubernatorial primary field led by moderate former US Representative Gwen Graham, the daughter of Bob Graham, a former Florida governor and US senator.
