In 2016, the Supreme Court vacancy left by Justice Antonin Scalia’s death may have been decisive in convincing conservative voters to support Donald Trump. National exit polls showed that 21% of voters said the Supreme Court appointment was “the most important factor” in their decision, and those voters favored Trump over his opponent, former Secretary of State Hillary Clinton. “Supreme Court nominations unite the Republican Party,” says Mike Davis, president of the Article III Project, a group that fights to confirm Trump’s judicial nominees. Now, as Trump trails former Vice President Joe Biden in national polls, “Judge Barrett’s nomination is helping President Trump climb out of the hole and it will put him in a place where he can stun the world again with an upset victory,” Davis says.
