The Republicans got a bounce out of their convention. The Democrats did not. Why? Elementary. The Republicans had something to say. The Democrats did not. Something always beats nothing.

The Democrats purposely chose a candidate with a 22-year history in elective office entirely barren of any distinction. Can you name a single significant bill that bears John Kerry's mark? A single important speech? A single legislative achievement? A single idea of any kind associated with Kerry's name?

The Democrats chose a candidate known for political calculation, a talent for nuance and an unswerving dedication to swerving constantly to avoid political risk. In other words, they chose a cipher.

Not a bad strategy when the news for the Bush administration -- the Iraq insurgency, Abu Ghraib, the Sept. 11 hearings -- was awful. Pick a cipher and make this a referendum on the president. A plausible idea, but it did leave everything up to chance. Worse, it leaves everything up to the other side.

How did the Democrats spend the four days at their convention? Saluting the Swift boats. Why? Because John Kerry has taken so many positions on Iraq and the war on terrorism that he has nothing believable or useful left to say. All he can say is "Vietnam."

In the bizarre midnight rant that he gave in Springfield, Ohio, minutes after the president's acceptance speech at the Republican convention, he went into a long denunciation of all that's gone wrong in Iraq. One waited for his alternative policy. What did he offer? "I defended this country as a young man, and I will defend it as president of the United States of America."

Pathetic. Douglas MacArthur, Curtis LeMay and George Wallace could have made an equal claim. What kind of qualification is that for the presidency?

At their convention, the Republicans had something to say. It was simple and clear: There is a war on, and we are tough enough to deal with it. Not because of what we did 35 years ago but because of how we have dealt with our various enemies for the past three years.

Now, some people will weigh the results of these three years and approve. Others will not. But at least this is a case -- a plausible claim that bears scrutiny and debate.

John McCain gave a serious and sober defense of the Iraq war on grounds of "realism" -- the prudential grounds that with the sanctions on Saddam Hussein collapsing, the choice was not between war and some imagined peaceful status quo but between war and a hugely unstable and gathering threat.
