Ok, lets talk about powers then.
Do "the people" have any powers that Congress doesn't have?
The Congress does not have the power to elect a Congress, nor does the Congress have the powers of the Executive, nor does Congress have the powers of the Judiciary.
The people, in contrast, have the power to elect a Congress and an Executive and through these delegates they also exercise their power to appoint a Judiciary.
Congress' only power is legislative.
