West Virginia voters are projected to approve a measure on Tuesday’s ballot to change the state’s constitution to outlaw abortion and prohibit any funding from covering abortions.

The successful amendment could come into play if the Supreme Court overturns Roe v. Wade, the 1973 court ruling that made abortion a constitutional right. If the court does overturn Roe, then the issue of abortion would be left to states. Anti-abortion advocates are bullish on the chances of overturning Roe after the confirmation of conservative Justice Brett Kavanaugh.
