They Challenged the Status Quo. On Tuesday, They’ll Find Out Who’s With Them.

• “I’m a survivor of a decade of childhood sexual abuse and also campus sexual assault.”

Ayanna Pressley, a Democrat from Massachusetts, has put her struggles and identity front and center in her campaign ads. She’s now poised to become the first black woman to represent Massachusetts in Congress after beating a 10-term Democratic incumbent, Michael Capuano, in the primary.

• “I’m a hard-core, card-carrying Tennessee conservative. I’m politically incorrect and proud of it.”

Representative Marsha Blackburn, who is seeking Bob Corker’s vacant Senate seat, would be Tennessee’s first female senator if elected. In her ads, she channels President Trump, calling Republican lawmakers weak and vowing to help repeal Obamacare.

• “This country says it was founded on fundamental values of justice, liberty and the pursuit of happiness, but these core beliefs are under threat.”

Ilhan Omar, a Democrat who’s heavily favored to win her bid for Congress in Minnesota, let her daughter do the talking in a campaign ad, flipping the script by presenting children as an asset, not a liability. If elected, Ms. Omar, a refugee, would be one of the first Muslim women elected to the House.

• “Opening, pushing and sometimes kicking through every door in my way.”

MJ Hegar, a Democrat from Texas, raised millions of dollars after her campaign ad titled “Doors” went viral; it has been viewed about three million times on YouTube. The ad focused on her military service, which includes three tours of duty in Afghanistan and a Purple Heart. She’s behind in the polls in her deeply conservative district and faces an incumbent, John Carter.
