She talked so slow and in a demeaning manner; my opinion.

That’s a characteristic of democrat speaker training provided by Burson-Marsteller public relations firm. Hillary uses it too. (So does Diane Sawyer.) Another Burson characteristic is gesturing with a loose fist when speaking. Visualize wagging your finger at someone but loosely tucking your index finger back. Burson tells their speaker trainees that wagging a straight index finger is stern, and creating a tight closed fist is threatening, so they created this lame gesture. Watch Jay Carney for this. He’s the king of the loose fist. A-holes all!
