People who attended the event said it was a very good speech any one can use selected tidbits of any speech to make the speaker look bad.
Whoever posted the video thought he was drunk. People attending the event are going to say he wasnt drunk because they already support him. Anything he says is great no matter what he does.
I think this blogger is extremely lazy. He takes spin from other sources and just regurgitates it without checking into its veracity. He has managed to mix two such stories in this thread.
So in other words, he adds absolutely nothing to the news and analysis process.
