In regard to Thursday nights debate with Hillary Clinton, Obama said it highlighted their differences on three key issues: U.S. Iraq war, universal health care and reducing the power of special interest groups and lobbyists.
Obama also expressed his concern over the latest employment numbers. There has been a net job loss in the U.S. for the first time since 2003. He says unemployment insurance needs to be expanded as part of an economic stimulus package.
"It is clear that the economy is slowing down and that families all across the country need urgent relief. They are concerned about loosing their homes and their jobs," said Sen. Barack Obama.
Just a few days ago Obama received a big endorsement from Senator Ted Kennedy. As Obama heads to other states Sen. Kennedy will rally supporters throughout California.
Obama also picked up the support of a large union in California which had endorsed rival John Edwards, who dropped out of the race this week.
