It turns out that SCOTUS appointments have had a long history of dividing American society. An excerpt:
9. Roger Taney (1836-64). Taney rose up the political ranks as Andrew Jackson’s right-hand man. Jackson tried to get him on the Supreme Court in 1835 but his nomination was rejected by anti-Jacksonian Whigs in the Senate. After the Whigs were swept away in the 1836 election campaign, Jackson renominated Taney, but this time for the position of Chief Justice, and he was confirmed 21-15 after a bitter debate in the Senate. The Taney court is responsible for the Dred Scott case that tore the fledgling republic apart, and for helping Jackson abolish the national bank. Taney and Lincoln clashed often, too, as Taney ruled that Lincoln’s suspension of habeas corpus was unconstitutional, but Taney never did go home during the Civil War and served out his term as Chief Justice until his death in 1864. He holds the second-longest tenure of any Chief Justice.
Please, read the rest, and try to remember: this divisiveness is a feature of the system, not a bug.
