No, they are not dumb.
You assume the have the same goals and fears we do.
They do not. Many of them fear the Media much more than they fear their voters. They know the Media has a very strong ability to sway voters.
You are absolutely correct. I believe in my heart of hearts that the grand majority of so called republicans are actually avid supporters of the One World Government bunch. They want Trump gone and their goals to continue. RINOs rule the party. They are no different than the commies. One and the same.
