McCain must already have been in sympathy with Khalidi's ideology, otherwise I doubt he would have given him more than a half million dollars (almost a half million on one occasion, and there were other occasions in which McCain gave him money).

On whether or not Obama was influenced by Khalidi's ideology, being someone's friend doesn't mean that they will absorb that friend's ideology by osmosis or anything. I have friends and relatives who are of the right wing, but so far, their ideology has not rubbed off on me. All people need to do to know where Obama stands on this particular issue is to look at his record. (A stance and a record that I do not agree with myself, incidentally.)
