4WD,Even if anyone were try to pull a Fidel Castro or Hugo Chavez on the United States, I don't see them being able to get congress to rewrite the Constitution, or getting the US military on their side to do a coupe.
Hey, there, e.r.m., long time no see. Welcome back. I hope you stick around.
The Left is rewriting the Constitution even now. It doesn't matter what the Constitution says, it only matters how the Constitution is interpreted. We are seeing that interpretation redefining what it means that Congress shall make "no law respecting an establishing of religion or prohibiting the free exercise there of". Shutting down church attendance due to the China virus is but an early example of such reinterpretation. The Left is on a role right now in "abridging the freedom of speech, or of the press, etc. And just wait till you see how the Left interprets the Constitution's statement that "the right of the people to keep and bear arms shall not be infringed", and what comes of that reinterpretation.
The Leftism is already infiltrating the US military. It won't take a revolutionary coup. You need to read up on Cloward-Piven Socialist Strategy. It is being implemented even today. The China virus, and the resulting economic collapse has provided the perfect avenue for it. The Left's proposal to forgive massive amounts of student debt, to mandate huge increases in minimum wage, to institute guaranteed annual income are but a few more Cloward-Piven induced strategies even if some of those supporting the Left do not recognize it. The effort of the Leftists in the areas of health care, energy production are side issues, but they result in absolute control of the population by the State. The influence of Leftism in education, in the media, in entertainment only enhance the push for full blown Statism, whether it goes by the name of Progressivism, Socialism, or Communism.
Once democrats manage to add DC and Puerto Rico as states, get rid of the electoral College and pack the Supreme Court, there will never be another republican controlled national House, Senate or Presidency. And the military will simply do what it is told. It knows where its funding comes from.
