Congressman Ron Paul finished in fifth place in the Iowa Caucus, with 10 percent of the vote. Former New York City mayor Rudy Giuliani picked up 4 percent of the vote. As Don Frederick notes:

An easily overlooked aspect of the Iowa caucuses — Ron Paul not only besting Rudy Giuliani, but doing so by more than 2-to-1 — sparked a trip down memory lane for us.

It was mid-May, and the former mayor of New York was riding high following one of the early debates among the Republican presidential candidates. The primo sound bite had been a snap to identify: Giuliani’s outraged, impassioned reply to Paul’s assertion that U.S. foreign policy, especially the periodic bombing of Iraq in the aftermath of 1991’s Gulf War, was to blame for the Sept. 11 attacks.

Giuliani, not waiting to be called upon, seized the moment by terming Paul’s comment “an extraordinary statement” and urging the Texas congressman to retract it (which Paul did not).
