Is Obama like MLK and JFK rolled into one?

This is a serious question. All were accused of being a communist. All three were young, well spoken and brought about hope for change. All drew/draw large crowds. Like JFK he’s a first term SEN. All had the love of the media. While we now have Holidays for both MLK and JFK, they were both murdered. People also mock JFK and MLK as thinking they were the Messiah because they dared to dream big. Will it take Obama giving his life for the hope he believes in before America can admit his greatness?
