Tonight on GRITtv, what does a belief in evolution have to do with the economy? Quite a bit. With John McCain’s selection of Sarah Palin as his running mate, the question of religious fundamentalism and its role in America politics is on the table in a major way. Environmentalist Chip Ward wrote recently that a Palin vice presidency would be, "the equivalent of launching a ’surge strategy’ in the Republican war on the environment."

Here to address the role of the evangelical right—their impact on the economy, nature, and science are Jeff Sharlet, author of The Family: The Secret Fundamentalism at the Heart of American Power, Heather Rogers, author of Gone Tomorrow: The Hidden Life of Garbage, Esther Kaplan, investigative editor at the Nation Institute and the author of With God on Their Side, and on the phone Congresswoman Diana DeGette.

We also have an interview with Michael Zweig, Director of the Center for Study of Working Class Life at Stony Brook University. An update on tomorrow’s protest on Wall Street from Code Pink’s Jodie Evans. You can find out more about what’s going on in your city at truemajority.org. Bring your junk to Wall Street. Finally, a performance and interview with singer/songwriter Leni Stern. All that and more on GRITtv.
