I think it's hilarious that you try to minimize the significance of mentioning Obama's full middle name, as if it were as innocuous as the "Fitzgerald" in John Fitzgerald Kennedy. Very rarely was the full "Fitzgerald" mentioned, it was either "JFK" or "John F. Kennedy" or just "Kennedy." The Republican supporters I cited (and believe me, they are but the tip of the iceberg) go out of their way to mention the middle name in full and almost as often as they refer to the candidate at all.
To those who say, "Well, it IS his middle name," I ask, how many times do you, in referring to ANYBODY, refer to them by their full name, including full middle name? How many times was Bush referred to as "George Walker Bush?" Cheney, I don't even KNOW his middle name. Clinton, almost never referred to by three full names, John Edwards, we don't even know the middle name, Harry S. Truman (I don't think the "S" actually stood for anything, FDR almost never referred to as Franklin Delano Roosevelt, Ike often Dwight D. Eisenhower, but you'd almost never hear the middle name. It's bullshit to claim that the name Hussain is used because "It IS his middle name." Nobody gives a shit what his middle name is, any more than anyone else's middle name - - it's used for one reason, to excite anti-Muslim prejudice.
There is no doubt the race card is in play. There's no doubt it is the Republicans who have put it in play. Whether it works or not will depend on how racist the American voters still are. If they're all as non-racist as has been claimed here, they'll see right through this ugly tactic and show their displeasure at the polls. If they're as racist as I think they are, they'll silently take this "Hussein" shit as vindication of their own racism and vote as their racism dictates.
