And why the president is technically elected by electors, and not directly.
And why federal justices have terms for life or until they choose to resign (barring they don't get impeached).
Smart decision by the founding fathers.
You really don't get it, do you? The people have all the power and gave some to the state and Federal governments. The people were NOT given power by the Constitution. They agreed to relinquish some of the power they had, not near as much as our "modern" politicos think, to the government. We (the people) gave the power to the government and we can take it away.
