"Sometimes the leak is so bad that even a plumber can't fix it." This was the concise summation of a cable political strategist the other day, after the third and final presidential debate. That sounds about right, and yet the race in its final days retains a feeling of dynamism. I think it is going to burst open or tighten, not just mosey along. I can well imagine hearing, the day after Election Day, a lot of "You won't believe it but I was literally in line at the polling station when I decided."

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.

There is now something infantilizing about this election. Mr. Obama continued to claim he will remove wasteful spending by sitting down with the federal budget and going through it "line by line." This is absurd, and he must know it. Mr. McCain continued to vow he will "balance the budget" in the next four years. Who believes that? Does even he?

More than ever on the campaign trail, the candidates are dropping their G's. Hardworkin' families are strainin' and tryin'a get ahead. It's not only Sarah Palin but Mr. McCain, too, occasionally Mr. Obama, and, of course, George W. Bush when he darts out like the bird in a cuckoo clock to tell us we are in crisis. All of the candidates say "mom and dad": "our moms and dads who are struggling." This is Mr. Bush's former communications adviser Karen Hughes's contribution to our democratic life, that you cannot speak like an adult in politics now, that's too austere and detached, snobby. No one can say mothers and fathers, it's all now the faux down-home, patronizing—and infantilizing—moms and dads. Do politicians ever remember that in a nation obsessed with politics, our children—sorry, our kids—look to political figures for a model as to how adults sound?

There has never been a second's debate among liberals, to use an old-fashioned word that may yet return to vogue, over Mrs. Palin: She was a dope and unqualified from the start. Conservatives and Republicans, on the other hand, continue to battle it out: Was her choice a success or a disaster? And if one holds negative views, should one say so? For conservatives in general, but certainly for writers, the answer is a variation on Edmund Burke: You owe your readers not your industry only but your judgment, and you betray instead of serve them if you sacrifice it to what may or may not be their opinion.
