WASHINGTON — The Supreme Court’s ruling Friday to eliminate the broadly supported constitutional right to abortion ignited a political firestorm in an already heated election year, landing less than five months from a slew of contests for Congress, statehouses and governor.

The Supreme Court’s historic decision enables states to ban abortion. It also allows Congress to outlaw abortion nationally, for the first time in a half-century, giving the winners of the 2022 elections new powers to determine whether abortion stays legal.

Democrats vowed political revenge at the ballot box, with President Joe Biden immediately seeking to channel the backlash by urging voters to put Democratic candidates in power so they can maintain a woman’s right to end a pregnancy.
