Does the US President or the congress or the Supreme Court change the Constitution without voting on changes?

Congress can amend the constitution, but not without a vote. They can also call a constitutional convention to rewrite a whole or part of the constitution, but again, not without a vote. Although, there are ways around the constitution.

For example, if congress passed an unconstitutional law and the president signed it, the supreme court may rule the law as unconstitutional, but because it is the president's job to enforce the law, he can disregard their ruling, even though this generally leads to a huge drop in popularity.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
