Barack Obama will now go on to defeat John McCain:

Sen. Barack Obama captured enough convention delegates Tuesday to make a historic claim to the Democratic presidential nomination, the first African-American to earn a major party's nod.

The first-term Illinois senator defeated what had once been the most powerful machine in the party. His rival, Sen. Hillary Clinton, the former first lady who sought to be history's first female nominee, saluted him. But she did not concede, even as she signaled openness to being considered as his vice presidential running mate.

Yes we can.
