Commentary: I was in the Navy when Eisenhower was President and later spent 30 years as a Federal employee. During that time, the Office of Personnel Management made it clear to me and other Federal employees the importance of the Hatch Act—which makes clear the consequence of promoting political views. The Act ensures that Federal employees are advanced based on merit rather than political affiliation.
Even though there are some exemptions for the President and Vice President under the Hatch Act—all Presidents (Democratic & Republican) I served under never attacked their opposition while performing their official duties. That is certainly not the case with the current President.
At an U.S. military base in Iraq on Christmas day--Trump signed MAGA hats, attacked Nancy Pelosi (Minority House Leader) by name for not supporting his Mexican wall, said that former Presidents were weak when it came to Mideast policy and claimed that the troops recently received a 10% raise (not true).
To me, Trump sounds like an Latin American Dictator who has his own Army. When I joined the military and went to work for the government I swore an oath to the Constitution—not a President or political party.
There could be serious future consequences to this aberration of political norms.
