Abortion is about to become a major midterm election issue, as conservative voters look to elect anti-abortion senators who can confirm Supreme Court justices to overturn Roe v. Wade. Susan B. Anthony List President Marjorie Dannenfelser tells Axios that "The future of Roe v. Wade is on the line this election without question."

Why it matters: More Republican senators would make it easier to pass stricter abortion laws on the federal level. With groups like SBA List getting involved in battleground Senate races, Democrats will be forced to start talking about the topic they're trying to avoid.
