In September 2020, President Trump introduced Amy Coney Barrett as a Supreme Court nominee of unparalleled achievement and unyielding loyalty to the Constitution, according to SCOTUSblog. The post recalls that moment to open a broader reflection on how appointees sometimes behave differently from what their nominators anticipated.
The essay's title, "When justices drift," points to a pattern in which judges move away from the ideological or political assumptions that surrounded their confirmation. Barrett is the entry point, but the piece treats her case as part of a larger story about judicial independence and the limits of presidential control over the Court.
Because this is a single essay, there is no opposing source to compare. It offers one interpretive lens: Supreme Court appointments are not a guarantee of future voting behavior, and justices can change over time.
