Stop giving up on the Dims not giving up. We all watched it. He didn't commit perjury or mislead the Senate. He said he drinks beer and likes beer and admitted he on occasion had more than he should have. An argument between him and Horse's A$$ about how much is too much and how often is too often is a matter of judgment and opinion, not a matter of fact subject, like 30 is more than 15.
Perjury is like saying I am married to so and so when in fact you are married to two other women instead.
