What Does He Know? And When Did He Learn It?

Suddenly, John Kerry is adopting a straddle position on the weapons of mass destruction issue.

The old John Kerry: "George Bush sold us on going to war with Iraq based on the threat of weapons of mass destruction. But we still haven't found them. ... We were misled about weapons of mass destruction."

The new John Kerry: "It appears, as they peel away the weapons of mass destruction issue - and we may yet find them," he told host Chris Matthews. "Look, I want to make it clear. Who knows if a month from now, three months from now, you find some weapons? You may."
