"To announce that there must be no criticism of the president, or that we are to stand by the president, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public." Theodore Roosevelt
For one thing, he's been against the Iraq war from the get-go. Hillary Clinton voted for it, as did Senators Joe Biden (D-DE) and former 2004 presidential candidate John Kerry (D-MA). All three will surely vie for the '08 nomination. The latest polls show that a majority of Americans want the U.S. to bring home the troops now. This growing anti-war fervor will be a major factor in the next primary election, and can bode very well for the former veep.
Additionally, Gore is Mr. Environment, and has been preaching the global warming gospel for 20+ years. Most recently he preached to the proverbial choir at the World Environment Day conference in San Francisco, a five-day U.N. gathering to promote pro-environment practices. A growing chorus of scientists believe the recent frequency of strong Category 4 and 5 hurricanes such as Katrina and Rita may be linked to global warming. They believe that rising global temperatures warm the oceans, which in turn fuel hurricanes and intensify their power. On this issue, Gore just might have a groundswell of very interested listeners for a change.
