Campaign Corner
I think if I were standing against Giuliani, I'd make a point of dropping the "Rudy" which makes him sound like a freckle-faced newspaper boy, and keep calling him "Rudolf", which makes him sound like a cross between a reindeer and, vaguely but just enough, Hitler.
You could also once in a while mistakenly pronounce his name Giulietta. But not more than once or twice. Far better to say the name in as Italian an accent as you can.
I have lots of other ideas if any of the campaigns want to get in touch. Like: why not pronounce Hillary's name as if she were the start of the word hilarious? Senator Hilari- Clinton! That would work.
