WASHINGTON (AP) — The Supreme Court will again wade into the fractious issue of abortion this week when it hears arguments over a medication used in the most common way to end a pregnancy, a case with profound implications for millions of women no matter where they live in America and, perhaps, for the race for the White House.

Two years after the Supreme Court overturned Roe v. Wade and cleared the way for bans or severe restrictions on abortion in many Republican-led states, abortion opponents on Tuesday will ask the high court to ratify a ruling from a conservative federal appeals court that would limit access to the medication mifepristone, which was used in nearly two-thirds of all abortions in the United States last year.

That decision to reverse Roe had immediate political consequences, with Democrats making the case that the court had taken away a right that women held for half a century and winning elections as a result. Even conservative-leaning states like Kansas and Ohio voted against abortion restrictions. If the court were to uphold restrictions on medication abortions it could roil the election landscape in races for Congress and the presidency.
