But who wins, and her margin of victory, could tell us a little about what Democratic voters are thinking as the party tries to capitalize on its narrow control of Washington and prepares for a tough 2022 midterms challenge.
If Ms. Turner wins, especially if she does so with ease, it would be a sign that the upstart progressive energy that propelled Mr. Sanders’s two presidential campaigns is not fading, as the movement seeks new national leaders to gradually succeed the 79-year-old Mr. Sanders. And it would most likely send to Congress another high-profile advocate for the left’s biggest priorities, like universal health care and far-reaching climate action.
If Ms. Brown wins, particularly if she does so by a large margin, it would signal that Democratic voters prefer a candidate more in line with the party’s standard-bearers in Washington, and are wary about electing someone with a history of criticizing those leaders. Or, as Sean McElwee, the executive director of the polling firm Data for Progress, put it, it would suggest that Democratic voters “are interested in voting for the person who’s going to go to work and they’re not going to have to think about ever again.”
In the other race, which Republican will win?
In the Republican race near Columbus, a crowded field of Republicans is vying to upset Mike Carey, an energy lobbyist who was endorsed by Mr. Trump. He was largely unknown until the former president threw his support behind Mr. Carey in early June and all but ensured that he would be the front-runner.
But the race is fluid, with more than 10 candidates running for the Republican nomination. Some of Mr. Carey’s rivals also have more established reputations in the district, the 15th Congressional, as well as the backing of prominent allies of Mr. Trump.
These rivals include Bob Peterson, a state senator who also operates a 2,700-acre grain farm and has the support of Ohio Right to Life, the state’s leading anti-abortion group. There is also Ruth Edmonds, who has a following among Christian conservatives and the endorsements of Ken Blackwell, a prominent conservative activist and Trump ally, and Debbie Meadows, an activist and the wife of Mark Meadows, Mr. Trump’s last White House chief of staff.
