There is this concept of politics as a dirty game. It's a difficult game but it doesn't have to be dirty. I think this is what we need to bring to politics. I think politics around the world has very often been captured by big interests - 'lobbies' they call them in the States.

My desire to curtail undue freedom of speech extends only to such public areas as restaurants airports streets hotel lobbies parks and department stores. Verbal exchanges between consenting adults in private are as of little interest to me as they probably are to them.

America's political system has evolved over the last 50 years in ways that have enhanced the power of business lobbies.
