Bailing on the man

Today I read about another leading GOP senator coming out against the Bush policy in Iraq and calling for gradual withdrawal of U.S. troops. But why did it take until the 2008 election was looming to bring these people to their senses? Backing the U.S. troops is a no-brainer, we all back the troops whatever they're doing. The policymakers are quite another matter. We should be endeavoring to do what's right, not what's politically expedient.
