Dempublican Joe Lieberman’s endorsement of John McCain was based on national security worries, he said, citing the “Islamist terrorists” who attacked us “on 9/11.”

Did Lieberman make his “9/11” reference to separate McCain from the self-proclaimed Knight of 9/11, Rudy Giuliani, who has about the same numbers in NH?

He/She must be alive and American. Is it Leno? Bill O’? Springer?
