NASHVILLE, Tenn. (AP) — The race to succeed retiring U.S. Sen. Lamar Alexander in November will feature a matchup between a Republican candidate endorsed by President Donald Trump and a Democratic single mother and Black activist who pulled off an astonishing upset victory over an opponent favored by the party establishment — with a campaign war chest of less than $10,000.

Former U.S. Ambassador to Japan Bill Hagerty fended off a challenge from Nashville trauma surgeon Manny Sethi in the Republican primary for the seat. Meanwhile, Marquita Bradshaw handily defeated Army helicopter pilot James Mackler, who raised more than $2.1 million and drew endorsements from the likes of the Democratic Senatorial Campaign Committee.

“We didn’t raise a million dollars, but the dollars that we raised came from hard-working people in Tennessee and around this nation,” Bradshaw told The Associated Press in an interview. “Some of them are housekeepers, some of them pushcarts from WalMart, some of them are scientists. But they are people who want us to head on and deal with the issues.”

The 46-year-old from Memphis will have an uphill battle: Republicans have held both Senate seats in Tennessee since 1994, and Trump remains popular enough in the red state that Hagerty mentioned the president at every turn.

“I have a very special person to thank. I just got off the phone with him backstage. That’s President Donald Trump,” Hagerty said during a victory party Thursday, accompanied by Sens. Marsha Blackburn of Tennessee and Tom Cotton of Arkansas. “You know, President Trump has had my back since before the beginning of all this.”

Bradshaw has said she has been “one job away from middle class and one job-loss away from poverty.” She said she was once under-employed, riddled with student loan debt and without adequate health insurance. Then she experienced a foreclosure and bankruptcy. She next goes up against a candidate who spent $9.6 million through mid-July.

“The progressive movement is undeniable!” Bradshaw tweeted after her victory. “Thank you all so much for your support and this victory. It’s time to put hardworking people first. Onward.”

Hagerty, a Nashville businessman, emerged from a tough challenge from Sethi to clinch his party’s nomination. Last July, Trump let Tennessee voters know he would back Hagerty for the seat, months before Hagerty declared himself a candidate. Sethi had already been running for about a month when Trump’s tweet turned the contest upside down.

Hagerty proceeded to ignore Sethi for most of the campaign, until back-and-forth attacks opened up a few weeks ago and never slowed down. Hagerty leveraged Trump’s endorsement to brush back attacks on his previous business and political ties to Mitt Romney, who was once the GOP presidential nominee and now, according to Hagerty, is a “weak-kneed” Republican senator who voted to convict Trump during the president's impeachment trial.

Hagerty had other big political names on his side beyond Trump. He had endorsements from Vice President Mike Pence, Senate Majority Leader Mitch McConnell, former U.N. Ambassador Nikki Haley, Blackburn and Cotton, while others backed him with campaign cash, including Sen. Alexander through his PAC and former Gov. Bill Haslam, for whom Hagerty served as state economic development commissioner.

Hagerty and Sethi differed little on conservative sticking points on immigration, gun rights, abortion opposition and harsh rebukes for Black Lives Matter.

Hagerty, who last month resigned from the board of a brokerage firm because the company expressed support for the Black Lives Matter movement, now faces a Black activist in November.

Bradshaw grew up in south Memphis and attended the University of Memphis. She has worked with community advocacy groups, environmental organizations and unions, including the Mid-South Peace and Justice Center, the AFL-CIO, the Sierra Club and Tennesseans for Fair Taxation. She has not held public office.

Bradshaw supports the Green New Deal, expanding Medicare, increasing the minimum wage to $15 per hour and universal background checks for guns, according to her website.

Bradshaw spent around $5,800 through March, the last time she reported any campaign finance activity, records show.
