There is a seating area for the public called a "Gallery". There's a gallery for the House and a gallery for the Senate. You should go through your member of Congress to get a pass for the gallery. If you want to see the House, contact your Representative. If you want to see the Senate, contact either of your Senators.

Teekno is right.

The passes are free, but you may have to stand in line when you get there because there is a limited number of seats in the gallery.

Tune in C-Span for a little while, and I am sure you will change your mind about sitting and watching politicians in the Capitol building - most of the time, they are a very boring group of people.

No Matter what party you choose just be a really good liar. You will get far.
