US Libertarian presidential hopeful Bob Barr speaks about recent Supreme Court decisions at the National Press Club in Washington on June 25, 2008. Barr was chosen on May 25 to be the Libertarian Party's candidate for November's presidential election, a move that could hurt Republican presumptive nominee John McCain. The Libertarian Party stands for non-interference by the US government in the personal and business lives of Americans, and advocates lower taxes, a smaller government and more individual freedom.
