President Trump has said that a major factor in the 2016 election was his promise to nominate a conservative justice to fill an open Supreme Court seat. He’s named two justices so far as President, shifting the court’s center of gravity to the right for a generation. Now, after the death of the powerful liberal Supreme Court Justice Ruth Bader Ginsburg on Friday, Trump faces the chance to name a third justice to the court. And that, say some Republican supporters, may animate Trump voters at a moment when he is trailing former Vice President Joe Biden in the polls. Having the conversation shift for the next two months to include a Supreme Court nominee “helps Trump and it helps Republican Senate candidates,” says Dan Eberhart, a Republican donor.
