It is due to several federal district court judges, appointed by Republican Presidents George H. W. Bush and George W. Bush, and Democratic Presidents Jimmy Carter. Bill Clinton, and Barack Obama, that the worst violations of the Constitution by Donald Trump have been prevented from being fulfilled.
On Trump’s travel bans against Muslims and others from several nations; on penalties against “sanctuary cities” which protect undocumented immigrants; and on banning transgender soldiers in the military, these judges have denounced the President for unconstitutional actions, and have been able to stop his destructive tendencies.
Eventually, the circuit courts and the Supreme Court will have to deal with much of the damage Trump has wrought, and there is no certainty of the outcome.
And Trump and the Republican Party in the Senate are in the process of ramming through a large number of judicial appointments, only needing 51 votes to confirm nominees.
These nominees in many cases are totally unqualified and augur a time of incompetent judges who will do great damage to the constitutional norms that Americans are accustomed to, including justice and equality of treatment under the law, which clearly, Donald Trump has no interest in enforcing.
This is another reason why the movement to force Donald Trump out of the Presidency as soon as possible is so significant for the health of the Constitution and Bill of Rights.
