He addressed Senate "President Pro Temporary" Byrd. I know it was just a slip and he didn't mean it, but it was a bit of a chuckle.
Having said that, the callers on C-SPAN after the speech were totally and completely stunning. At least two democrats called in say President Bush and his speech changed them completely. One said she is no longer a democrat or a republican, but an American. Another said she was inspired. Awesome.
Wow. BTW, I think he came pretty close to saying "pro tempore".
