Sarah Palin, Wordsmith?

America's favorite clown, Sarah Palin, has coined a neologism: refudiate. Is this a combination of "refute" and "repudiate"? It's a neat combination, I must say, but I really don't think that Palin had this as a new word in mind when it passed from the gray space in her mind to her lips. It was just a malapropism, but of course, never one to admit she's wrong, Palin rationalized her slip as creative license, even daring to say that the estimable Shakespeare made up new words.
