Democrat Kyrsten Sinema's unbreakable hold on Maricopa County, along with overwhelming support for her from Martha McSally's Tucson-based congressional district, gave her an electoral edge Republicans could not erase in the race for Arizona's open U.S. Senate seat.
Sinema's systematic play for moderate Republican voters, independent voters and suburban women anxious about the polarizing politics in the era of President Donald Trump gave her an advantage in the state's urban areas that was too great for McSally to overcome.
Sinema maintained her lead over McSally on Monday, and grew it to 1.7 percentage points, with the latest drop of early ballots, again defying the narrative from McSally's campaign that the Republican would perform well enough in the waning days of ballot-counting to remain competitive.
In doing so, Sinema is on the cusp of vanquishing Republican's hopes of hanging onto the Senate seat, which U.S. Jeff Flake is vacating.
Sinema led McSally by 38,197 votes as of 5 p.m. Monday. When all of the votes are counted and the race is called, Sinema is on track to become the first woman in the state's 106-year-old history to take a seat on the floor of the U.S. Senate.
"The Sinema campaign did the math that they needed to do to win and did everything to get there, and didn't allow themselves to get distracted" by responding to Trump's latest tweets or news of the day, Democratic strategist Andy Barr said. "She had a very narrow path and needed to do everything right to win, and did it."
