Blogger Andrew Sullivan was very happy with the results:
To my mind, Obama dominated Romney tonight in every single way: in substance, manner, style, and personal appeal. He came back like a lethal, but restrained predator. He was able to defend his own record, think swiftly on his feet, and his Benghazi answer was superb. He behaved like a president. He owned the presidency. And Romney? Well, he has no answers on the math question and was exposed. He was vulnerable on every social issue, especially immigration. And he had no real answer to the question of how he'd be different than George W Bush. I'm excitable - but sometimes politics is about emotion as well as reason. And my view is that Obama halted Romney's momentum in its tracksIf Obama had not performed to this level, the election would have been effectively over. Now, it's game on.
