“Republican White House long shot Mike Huckabee cast himself as the New York Giants of political candidates, a scrappy David hustling to knock off Goliath.”

“Your servant has killed both the lion and the bear; and this uncircumcised Philistine will be like one of them, since he has taunted the armies of the living God.”
—David (1 Samuel 17:36)

So maybe Giuliani was like the lion, and Romney was like the bear?
Where is the barf alert?
