The International Socialist Organization has branches across the country. Our members are involved in helping to build a number of struggles: the movement to stop the war on Iraq, fights against racism and anti-immigrant scapegoating, the struggle for women's rights like the right to choose abortion, opposing anti-gay bigotry, and standing up for workers' rights. We are committed to building a left alternative to a world of war, racism and poverty.

Contact the ISO, or find an ISO branch near you, and come to a meeting.
