This is where it's going. Can the President undermine the system enough to scoop up and arrest say, Democratic Congresswomen after declaring that their politics are anti-American and that therefore they are enemies of the United States of America?To find that you support illegally expelling United States citizens because you don't like their politics is completely unsurprising.
I'm betting that there is a way and that it is possible.
Why? McCarthyism.
They've done it before and the US Constitution and Bill of Rights turned out to be so much bum wipe.
