Big Surprise...Mayor Daley Backs Obama for U.S. Senate

The two Democrats had a private meeting Monday in Chicago. Obama says he plans to focus on concrete proposals on housing, jobs and education and stay away from negative attacks in his campaign.

Daley says he's willing to help with fundraising and campaigning in Obama's bid to win the Senate seat that's being vacated by retiring GOP Senator Peter Fitzgerald.

The Republican nominee Jack Ryan has criticized Obama for being too liberal for Illinois, but Obama says he may not agree with some legislative proposals sponsored by Republicans, but that he will look for their common ground and focus on the needs of Illinois.
