"It's a rule that George W. Bush's chief political strategist Karl Rove knows well. And it's a rule that he and Bush -- and events -- have put into operation over the last few weeks. For months, the central issue of the off-year election has been, Hasn't Bush kept us too long in Iraq? Now, the issue seems to have become, Who can keep us safe against the Islamofascist terrorists who want to kill us and destroy our society?

The first question tends to help the Democrats. The second tends to help Bush and the Republicans."
