From July 2003 interview with Bill Moyers on NOW:
STEWART: No. They vote… less than 50 percent of the country. The country is, look, the general dialogue is being swayed by the people who are ideologically driven.
The five percent on each side that are so ideological driven that they will dictate the terms of the discussion. The other 90 percent of the country have lawns to mow, and kids to pick up from schools, and money to make, and things to do. Their lives are, they have entrusted… we live in a representative democracy.
And so, we elect representatives to go do our bidding, so that we can get the leaves out of the gutter, and do the things around the house that need to be done. What the representatives have done over 200 years is set up a periphery — I think they call it the Beltway — that is obtuse enough that we can’t penetrate it anymore, unless we spend all of our time. This is the way that it’s been set up purposefully by both sides. In the financial industry, as well. They don’t want average people to easily penetrate the workings because then we call them on it.
