John McCain won the debate, and he did it by making the case more effectively than he has in the past that Barack Obama will raise taxes, when "now, of all times in America, we need to cut people's taxes." He also scored Mr. Obama on his eloquence, using it against him more effectively than Hillary Clinton ever did. When she said he was "just words," it sounded like a bitter complaint. Mr. McCain made it a charge: Young man, you attempt to obscure truth with the mellifluous power of your words. From Mrs. Clinton it sounded jealous, but when Mr. McCain said it, you looked at Mr. Obama and wondered if you'd just heard something that was true. For the first time, Mr. Obama's unruffled demeanor didn't really work for him. His cool made him seem hidden.
