You don't have to be that good to fend off a committee of showboating senatorial blowhards. Hillary Clinton demonstrated that a week or so back when she unleashed what's apparently the last word in withering putdowns: What difference does it make?

"Rightful liberty is unobstructed action according to our will within limits drawn around us by the equal rights of others. I do not add 'within the limits of the law' because law is often but the tyrant's will, and always so when it violates the rights of the individual." Thomas Jefferson
