Long-shot presidential candidate Mike Gravel told supporters Wednesday he is leaving the Democratic Party to join the Libertarian Party. Gravel, a former Democratic senator from Alaska, said in an e-mail that the Democratic Party "no longer represents my vision for our great country." In an email, he wrote, "It is a party that continues to sustain war, the military-industrial complex and imperialism - all of which I find anathema to my views."
