Barbara Boxer: “Senator Vitter made a good point when he showed the great progress that the Clean Air Act has achieved.”

The way the Senate works, as you know, it’s a supermajority to get anything done. It has nothing to do with age.

It's up to his colleagues to determine if they want such a coward, such a liar, to be their leader, and or maybe even speaker.

Frankly, anyone who runs on that as an issue should be defeated, overwhelmingly by everybody.

This is a sad moment, we always had two parties, one was to the right of center, one was to the left of center, and we never had a party, so extreme and so willing to become the party of grievance and anger and division.
