Abbott and 25 other red state extremist Governors are openly defying: There are many factors that led to this point. One is the reigning Republican ideology of Trumpism, which holds that only conservative electoral victories, conservative laws, and conservative governments are legitimate and must be obeyed—the ideology that led a mob to ransack the Capitol to overturn an election. Another is the steady drumbeat of catastrophizing right-wing propaganda about the recent rise in migrants at the border, which seeks to validate extreme responses, including violence and lawlessness.

When the Court sided with the Biden administration, it was a 5–4 split, with Justices John Roberts and Amy Coney Barrett joining the three Democratic appointees. This should have been a unanimous ruling; for more than a century, the Supreme Court has held that the federal government has jurisdiction over immigration law in most cases and that the states cannot usurp that jurisdiction just because they disapprove of federal policy. Abbott is now thumbing his nose at the federal government and, by extension, the authority of the high court itself, and four Republican appointees—Brett Kavanaugh, Clarence Thomas, Samuel Alito, and Neil Gorsuch—are saying: Go right ahead.
