The DNC makes an honest-to-goodness smart move: Barack Obama, the Democratic Party's candidate for the Senate in Illinois, will deliver the keynote address at the convention, officials announced Wednesday. Obama, a law professor and state senator, will speak on July 27, the second night of the convention, with Sen. Edward Kennedy, D-Mass. Obama will talk about the future of America that a Democratic administration would provide, along with the need to make jobs, families and communities top priorities in the lives of Americans.
