Take a look at the oath for military folks
For Officers
"I, _____, do solemnly swear (or affirm) that I will support and defend the Constitution of the United States
against all enemies, foreign and domestic;
that I will bear true faith and allegiance to the same;
and that I will obey the orders of the President of the United States and the orders of the officers appointed over me, according to regulations and the Uniform Code of Military Justice.
So help me God." (Title 10, US Code; Act of 5 May 1960 replacing the wording first adopted in 1789, with amendment effective 5 October 1962).
So the Prez (current or in former times) comes in - what - 4th place and then only if regulations and the UCMJ is obeyed.
Lots of interesting fiction based on a variation of these as a premise.
I don't think we have a lot to worry about until we see the outcome of the next set of Congressional races. You all, of course, may chose the think otherwise, as is your right.
Free elections in th e US are a thing of the past. IMHO the last free election was in 2004.
When you consider ACORN, money from Arab countries to democrats and the WH incharge of the 2010 census we are toast.
I think the order’s need to be constitutional.
