Obama's Night??MLK's night?? McCain's night??

Last night was certainly Barak Obama's night. Speaking in front of a crowd of 70,000 + and on the anniversary of MLK's speach really was something special. I liked that he incorporated parts of the speech in his own (but it was not overkill). From a pure oratory evaluation he did a fabulous job presenting his speech. I really believe it flowed well in terms of his organization of ideas. I was really intrigued however by McCain's "positive" add. What was the main motivation behind that? Was it heart felt and that he honestly wanted to congratulate Barak? Was it to brush off some of the criticism he has been under for all his negative adds? Or was it to do exactly what it is doing to my blog....take away from reflection about Obama's speach? HMMMM
