If you want a picture of the future, imagine a boot stamping on a human face—forever.
— George Orwell
Chief Justice John Marshall established that authority in Marbury v. Madison.
The 1803 decision has remained, with few exceptions, unquestioned ever since.
But the Trump-appointed justices don't care. They'll readily sacrifice Marbury for the sake of unborn fetuses—and to consecrate their definition of civil and personal rights: namely, that there are none.
Trump's favorite president, the demagogue Andrew Jackson, also readily sacrificed Marbury.
In 1832, the Court decided in Worcester v. Georgia that the Cherokees in Georgia had a legal right to their land, by virtue of a federal treaty.
But Jackson disagreed and in 1838 used the military to remove the Cherokees to concentration camps in Oklahoma.
Rather than use his power to carry out Worcester v. Georgia, Jackson violated the Court’s decision, signaling that he, not the Court, is the unquestioned authority in matters of Constitutional rights.
So, if the Court overturns Roe, you can expect its legitimacy to fall into question and fade.
And, if re-elected, you can fully expect Trump to use the military to quash citizen's rights.
