I expect Obama to be more aggressive in tonight’s debate. However, there’s only so much he can do. Even at his best, he’s not outstanding. He’s not Bill Clinton. He’s not that quick on his feet. Ad libbing is not his strong suit. Indeed, when he does speak off-the-cuff, he tends to make gaffes.
I expect him to memorize some applause lines for the debate, but that’s about it.
