By not confronting, arresting and prosecuting rioters, these Dem mayors not only fail to uphold the Constitution, but do so at a foundational level. They violate the Preamble of the U.S. Constitution, which is the stated purpose of government and their office.
Justice is not being utilized to insure our domestic Tranquility. Our common defense is not defending our general Welfare or our Liberty.
We need to hold their feet to the fire when they violate The Oath of Office! Make it mean something DAMMIT!
I suspect they are more like a placeholder.
