During his first debate with Mitt Romney, Barack Obama seldom looked directly at Romney. He seldom contradicted Romney. He never raised his voice to Romney. He never really challenged Romney. So what happens in the second U.S. presidential debate? OBAMA GETS HIS MOJO BACK!!! He came out bristling for a fight. This time Obama's in charge. He dominates the fight, provides the drive, the passion. This time, no deference.
