I disagree with the author. I don’t think Justices Scalia, Thomas, and Alito had an obligation to attend based on tradition or symbolism.
When the President of the United States of America regularly behaves as a dictator and tyrant who circumvents the United States Congress and the United States Constitution, it is incumbent upon those whose duty it is to uphold the Supreme Law of this land to stand upon their absence from the State of the Union Address as an act of symbolism.
Barack Obama does not respect the majesty of the United States Constitution. Justices Scalia, Thomas, and Alito should not pretend otherwise.
I'm with you.
Good point. Although not an ideal scenario, enmity is better than an acquiescing merge among the three branches of government.
