well I have a feeling that after the mayor of New York seemingly managed to upset so many with his attitude to the floods by saying that the main focus now should be on the marathon, which should go ahead. (it's strange for me cause this is the way London handled the 7/7 bombings, but I think he didn't approach the let's focus on the positives angle with any tact. He then threw his support straight behind Obama. Now the one thing this could cause is a subconscious linking of negativity between the two people. However, I feel Obama gets blamed for a lot like the war and the debt, neither of which were his fault (both caused before his election). So to answer your question it shouldn't, but I have a sneaking suspicion it will.
