I did not get to see his rebuttal live. Now that I've heard it, I have to say I was somewhat disappointed. The content of the speech was great, but the delivery was poor.
Now, I know that Jindal has never been on a stage like this before, giving the Republican rebuttal to a State of the Union, especially when it is delivered by a smooth (teleprompter-enhanced) speaker like Barack Obama. But, it sounded like Bobby Jindal was talking to a class of schoolchildren.
In that line of thinking, here's a great post by Matthew E. Miller at Race42012. He refers to a paper written by Winston Churchill in 1897, which is quite interesting to read. The Republican Party has not had a great orator since the Great Communicator.
Bobby Jindal has many years ahead of him to improve his speaking abilities. He has some massive intellectual firepower, and if he would polish his oratory skills, he could become a powerful speaker.
