In a stunning display of IOKIYAR (It's OK If You're A Republican), McCain said we're wasting troops' lives:

Discussing the war with Letterman, McCain repeated his assertion that U.S. troops must remain in Iraq rather than withdrawing early even though the war has been mismanaged.

"Americans are very frustrated, and they have every right to be," McCain said. "We've wasted a lot of our most precious treasure, which is American lives."

In February, Democratic presidential candidate Barack Obama described the lives of troops in Iraq as having been "wasted" but then apologized a day later for making what he called "a slip of the tongue" that he said was not meant to diminish their sacrifice.

So far, McCain has yet to apologize.
