Couldn't have said it better myself. Heaven knows I've been trying.

How can Kerry persuade moderates to throw out Bush? By turning the president's message against him. Bush is steady and principled. ....

From foreign to economic to social policy, Bush's record is a lesson in the limits and perils of conviction. He's too confident to consult a map. He's too strong to heed warnings and too steady to turn the wheel when the road bends. He's too certain to admit error, even after plowing through ditches and telephone poles. He's too preoccupied with principle to understand that principle isn't enough. Watching the stars instead of the road, he has wrecked the budget and the war on terror. Now he's heading for the Constitution. It's time to pull him over and take away the keys.
