Senator Obama needs to pound this message home;  We as a nation can't afford to continue this failed Iraq policy.  Such a message appeals to various constituencies, to anti-war democrats to independents to fiscal responsible republicans to security moms and many others. 

The Iraq policy weakens our national security.
The Iraq policy weakens our military.
The Iraq policy weakens our economy.
The Iraq policy weakens our ability to invest in America.
The Iraq policy weakens our National Guard.
The Iraq policy weakens our image abroad.
The Iraq policy takes our focus off of Afghanistan.
The Iraq policy prevents us from rebuilding our infrastructure.
The Iraq policy prevents us from having national health care.
The Iraq policy increases our national debt.
The Iraq policy damages our national pride.

McCain, by his own choosing has become the face of the Iraq war.  It should be made crystal clear that he represents the continuation of this failed war policy.  We can't afford this policy.  We can't afford McCain.
