In 38 years since Earth Day was first established, global warming has been identified as the biggest risk to the planet. All three candidates for president say the US must lead the way in dealing with climate change. What do they propose? We hear about cap-and-trade, subsidies for alternatives like solar and wind and nuclear power. Also, the Supreme Court hears a challenge on the McCain-Feingold Campaign Reform Act, and President Bush turned up on a game show last night. We talk about politicians and prime time TV.
