WASHINGTON (CNN) – Democratic presidential candidate Barack Obama is stepping up his effort to differentiate himself with rival Hillary Clinton on the issue of Iran Tuesday, sending a postcard to Iowa voters criticizing those who supported a recent Senate amendment that he claims "raises the risk of war with Iran."
The September 27 amendment in question, sponsored by Sens. Joe Lieberman, I-Connecticut, and Jon Kyl, R-Arizona, calls for labeling the Iranian Revolutionary Guard a terrorist organization. Clinton voted for the amendment while Obama missed the vote. But the Illinois Democrat has repeatedly said he is against the idea.
"Barack Obama is the ONLY major candidate for president to oppose both the Iraq War from the very start and the Senate amendment that raises the risk of war with Iran," the postcard states. "While other Democrats voted for the Kyl-Lieberman Amendment, Barack Obama opposed another Bush foreign policy fiasco."
Obama is also quoted in the postcard saying, "Why is this amendment so dangerous? Because George Bush and Dick Cheney could use this language to justify keeping our troops in Iraq as long as they can point to a threat from Iran. And because they could use this language to justify an attack on Iran as a part of the ongoing war in Iraq."
The campaign would not reveal the number of postcards it is sending.
Clinton has denied the terrorist labeling could increase the risk of war with Iran, arguing it instead allows for tougher sanctions.
