Just to clear up a few facts, of which John McCain is rarely in command, these days:

FactCheck.org: Soft on Iran

McCain implies that Obama doesn’t think Iran’s Islamic Revolutionary Guard Corps is a terrorist organization. That’s wrong. Before the Kyl-Lieberman amendment was introduced, Obama cosponsored a bill that called for the IRGC to be designated as “a Foreign Terrorist Operation.” Obama was one of 72 cosponsors of the Iran Counter-Proliferation Act, . . .The McCain campaign notes that the Iran Counter-Proliferation Act has yet to come to the floor for a vote. But that doesn’t change the fact that Obama’s sponsorship put him on record in favor of labeling the IRGC a terrorist organization, contrary to McCain’s insinuation.
