President Ronald Reagan nominated the Supreme Court justice who upheld Roe v. Wade. President Trump could nominate the justice who overturns it.

That’s how unpredictable the politics of the Supreme Court can be. Reagan, the most conservative president since the New Deal, arguably did more than any other single political figure to make the Republican Party pro-life. President Trump, widely assumed to be a liberal Trojan horse during the 2016 GOP primaries, was until recently pro-choice.
