Obama's Language in Healthcare Speech- Revolutionary?

In our American Studies class, we were discussing President Obama's adress to Congress and the language he used in it. A transcript and video can be found here. In class we discussed how bad it was to use the word 'lie' in a speech, and how Obama was the first president to do so. And also he referenced famous Republicans like John McCain, which I found quite interesting. What is he trying to do using this language, I wondered. He could just be living up to the expectation that he is a sort of 'hip and new' kind of president who is going 'change' the whole country. Or is he doing something smarter? Perhaps Obama is referencing Republicans more cleverly, to get the Republicans in Congress to listen to him. Maybe he is trying to show that its not about Liberal or Conservative, but that we're all under one flag regardless of political views. Is Obama trying to bridge the gap between the two political parties? Or is there another motive at work here? Also the way he uses the word 'lie', Mr. Bolos claimed that it was the first time a president used the word lie. Whats up with that? What does he stand to gain by using such a controversial word?
