and better! The last about 15 -20 mins I had a bit of tears in my eyes. I'll probably watch that part again.

Intelligent, and empathy/compassion, and vision.

MSNBC post speech - they pointed out the additional
things he added extemporaneously making it more personal, connecting.
Lawrence talked about his voice modulation's effectiveness.

And I can see that the polling had been very positive.

1. Did anyone catch that disruptive cough that was suspiciously loud?

I can't remember Biden's exact words, but the gist was that our country could fall back into the environment we just worked our way out of if we aren't vigilant. He repeated his words, and someone coughed so loudly I just had a feeling that it was a Republican trying to voice his disapproval.

you certainly could be very right!
Wouldn't put it past one of them.

He seemed to be 20 years younger at times.
