“Sen. Martha McSally had incurred weeks of unchecked attacks from Democratic groups, and the Arizona Republican’s allies are pleading for help,” the Washington Examiner reports.

“Since early September, Advancing Arizona has targeted McSally with a barrage of advertising as part of a $1.4 million television buy from the so-called dark money group that runs through late November. Need to Impeach, a super PAC, is chipping in an additional $134,000 in cable and digital attacks as Democrats in the House of Representatives accelerate an impeachment inquiry into President Trump.”

Mark Kelly (D), the retired NASA astronaut who is vying to unseat Sen. Martha McSally (R-AZ), “outraised her for the third straight quarter and has eclipsed his first two previous fundraising quarters,” the Arizona Republic reports.

“Kelly raised more than $5.5 million during the third quarter, his campaign told The Arizona Republic on Monday, bringing his total raised to nearly $14 million.”

Daniel McCarthy (R), who is challenging Sen. Martha McSally (R-AZ) in the Republican primary, suggested the United States annex Mexico, RealClearPolitics reports.

Said McCarthy: “There is a process to become states for the United States. Clearly 30 million Mexican illegal immigrants want to be United States citizens, probably half the country wants to be United States citizens.”

McCarthy also suggested that adding some “beachfront property” to U.S. territory might be nice.

Arizona GOP chairwoman Kelli Ward said in a fundraising email that the GOP would stop U.S. Senate candidate Mark Kelly (D) “dead in his tracks,” the Washington Post reports.

“Ward’s choice wording stands out not only because Kelly is an ardent gun control advocate, but because he took up the cause after his wife, former congresswoman Gabrielle Giffords, survived an assassination attempt in which a gunman killed six people and left Giffords with traumatic brain injuries.”

Businessman Daniel McCarthy (R) announced his intention to run against Sen. Martha McSally (R-AZ) in the Republican primary for the U.S. Senate in 2020, ABC Arizona reports.

“McCarthy is capable of putting tens of millions into the race according to a source close to the campaign.”

A new OH Predictive Insights poll in Arizona shows Mark Kelly (D) leading Sen. Martha McSally (R) in the U.S. Senate race, 46% to 41%.

Key finding: “McSally has fallen behind, the poll suggests, as President Trump’s standing takes a hit in Arizona. Just 47% of likely voters in the state approve of Trump’s job performance, down from 50% in May and 54% in October.”

“Federal appeals-court judges have agreed to decide whether Sen. Martha McSally (R-AZ) can continue to serve until the 2020 election without having been elected to her seat by voters,” the Arizona Republic reports.

“In December 2018, McSally was appointed by Gov. Doug Ducey (R) to fill the Senate seat vacated by the Aug. 25, 2018, death of veteran Sen. John McCain (R-AZ). Now, McSally and Ducey are defendants in a lawsuit filed by a small group of Arizona voters from across the political spectrum that claims it’s unconstitutional for McSally to serve as senator for 27 months without being elected.”

“Arizona Republican Chairwoman Kelli Ward said she wishes GOP elected officials, specifically Sen. Martha McSally (R-AZ), ‘would just be quiet’ when they disagree with President Trump,” according to audio obtained by Phoenix New Times.

“Ward’s criticism of McSally highlights the delicate balance faced by Arizona Republicans who hope to maintain support among Trump’s base as well as the moderate wing of the party.”

Mark Kelly (D), the retired astronaut who is hoping to unseat Sen. Martha McSally (R) in Arizona’s 2020 Senate race, raised $4.2 million during April, May and June, exceeding his first-quarter fundraising, the Arizona Republic reports.

Sen. Martha McSally (R-AZ) “has grown fearful of a 2020 primary challenge in recent days, kicking off a flurry of efforts to protect her at the highest levels of the Republican Party,” Politico reports.

“In a series of conversations with senior Republicans including President Trump, the senator has raised alarms about Daniel McCarthy, a skincare company executive who helped bankroll Trump’s 2016 campaign. McSally, who was appointed to her seat in early 2019 after losing a 2018 Senate race, faces a treacherous special election next year in a state that’s growing increasingly friendly to Democrats, and Republicans worry that a primary fight will further complicate her prospects.”

“Republicans are promising to do everything they can to obliterate Roy Moore in the Alabama Senate primary,” Politico reports.

“A push is underway to get President Donald Trump involved in derailing Moore. Republicans are actively moving to recruit Jeff Sessions to run for his old seat. And GOP leaders are warning the party will jeopardize perhaps its only chance at picking up a Senate seat next year if they let Democrat Doug Jones get his favored match-up.”

Said Sen. Martha McSally (R-AZ): “Give me a break. This place has enough creepy old men.”

A new OH Predictive Insights poll in Arizona shows Sen. Martha McSally (R) just ahead of challenger Mark Kelly (D), 45% to 44%.

Rep. Ruben Gallego (D-AZ) will not run for the U.S. Senate in 2020’s special election, he told the Arizona Republic, clearing the path for retired astronaut Mark Kelly (D) to take on incumbent Sen. Martha McSally (R-AZ) without a potentially bruising primary fight.

“Gallego’s decision will disappoint progressive Democrats, who represent the left flank of the party and are especially hostile toward President Trump.”

A new OH Predictive Insights poll in Arizona finds Sen. Martha McSally (R-AZ) leading new challenger Mark Kelly (D) by just two points, 46% to 44%.

That edge is well within the poll’s 4 percentage point margin of error.

Mark Kelly, former astronaut and husband to former Rep. Gabby Giffords (D-AZ), released a video announcing his campaign to challenge appointed Sen. Martha McSally (R-AZ) In 2020.

USA Today: “McSally is considered one of the most vulnerable Republican senators heading into the 2020 election. McSally is a former Air Force pilot and was the first woman to fly combat missions.”
