Are Representatives and Senators elected by popular vote?

Yes, and we have had direct, ballot-oriented election of senators for many decades. What is somewhat amiss is the Cabinet ministers. these are all Presidential hand-picks and the cabinet is not even discussed or implied in the Constitution. when I was a kid i was turned off by frequent news coverage of ( secretary of state Dean RusK) on the radio, what is this guy, a typewriter jockey for the Prez? The diplomat, was of course an appointed official, a button man. look at Hitler and Goebbels and the other Garrison-hatted gangsters who ran Nazi Germany/ is our system- and some aberrations like Nixonism- really that superior?
