Chris Mathews, in his obvious haste to destroy Palin,
mocked Palin for saying that the Vice President presides over

incorrect.
Here is the excerpt from the US Constitution clearly stated.
Article. I. - The Legislative Branch
Section 3
The Vice President of the United States shall be President of the Senate, but shall have no Vote, unless they be equally divided.
