What is his 'normal speech'? I've heard him speak everything from Harvard grad to NYC ghetto and everything in between. Will the real BHO step forward. . . and get hit by a bus please!
And that's my final answer!!
His cadence and tone were different. I have never heard him with a plaintive pleading transitioning into a whisper. But when he wanted an applause, that is exactly what he did. He did not move into jive/ghetto tonight.
