I go into some of the reasons in Bloomberg Opinion.
Four of the last 14 vacancies on the Supreme Court arose when different parties controlled the White House and a majority in the Senate. In those cases, the president’s initial nominee didn’t make it through half the time. When the president and the Senate were allied, on the other hand, 9 of 10 initial nominees were confirmed.
That’s the simplest explanation for why Judge Amy Coney Barrett is about to be confirmed to the Supreme Court: Republicans have the votes. What the balance of power doesn’t explain is rising public support for Barrett. . . .
