Obama supporters claim that their man is a supporter of Israel. Ralph Nader disagrees.

Nader credited Sen. Barack Obama (Ill.), who leads the Democratic nomination race, with being "the first liberal evangelist in a long time." But Nader said Obama's "better instincts and knowledge have been censored" by the demands of the campaign.

"He's leaned, if anything, toward the pro-corporate side of policy-making," Nader said. The question is, he added, "Do you have the fortitude to stand up against the corporate powers ... and get things done for the American people?" Obama, he said, has also erred on foreign policy. "He was pro-Palestinian when he was in Illinois," Nader said. "Now he's supporting" the Israeli government's policies, he added.
