Rush? There’s no need to rush. According to Wikipedia:
Kennedy was confirmed 65 days after his nomination. Thomas was confirmed 99 days after his. For Ginsburg it was a mere 50 days. Breyer was 73. Roberts (a bit odd because it shifted from Associate to Chief Justice partway through) was 23 or 39 days. Hell, let’s add them together and call it 62 days. Alito was 82. Sotomayor was 66, Kagan was 87 and Gorsuch was 65.
The midterms are in 132 days. President Trump could spend an entire month contemplating who from his list he’d like to select and the Senate could give that person a longer nominating process than any of the currently-serving justices, and it could still all be wrapped up before the midterms.
