Senate Republicans are readying for a vote next week on a late-term abortion bill. And while it’s unlikely they will have the votes to pass it, abortion opponents say the measure could play a role in the 2018 midterm elections.

The bill would ban abortions after the 20-week mark, while providing exceptions for rape, incest or the endangerment of a woman. It passed the House along party lines last year and has been waiting on a Senate vote.

However, with a 60-vote threshold for passage, Republicans face a tough path ahead. The legislation was recently listed as a top priority of anti-abortion groups.

“We’re going to take it up Monday on the Senate floor,” South Carolina GOP Sen. Lindsey Graham said during a press call about the bill Thursday.

“There are only seven countries left — just seven — that still permit elective abortion after 20 weeks, including us, unfortunately, China and North Korea,” Senate Majority Leader Mitch McConnell said on the floor earlier Thursday. “I look forward to voting to advance this bill next week.”
