Democrats in Washington, who face stiff headwinds in defending their majorities in Congress in next year’s elections, see a new opportunity to motivate voters who may have taken abortion rights for granted.

And Republicans are dealing with an unsettling new political landscape after having promised to outlaw abortions for decades to motivate their base.

Joshua Wilson, a political science professor at the University of Denver, said Republicans have had a “safe space” for years, because their vow to outlaw abortion was seen as an empty promise by both the left and the right as a result of the support for legal abortion during the previous Supreme Court regime.

Now, that safe space is gone.

“Under Trump, the Supreme Court context changed dramatically. So suddenly you’re in this context where the court might roll back abortion rights,” Wilson said. “That makes the politics more dangerous for Republicans.”
