You miss out, my friend. You have not experienced the posturing politic. You were not compelled to hear someone say that it is madness to continue to do the same thing and expect a different result. Mostly, this statement was made in order to corner and embarrass the left, but it understands political madness incorrectly. Political madness seems more to be continuing to do the same thing, to insist upon the same policies, no matter what the consequences. Colbert once said of George W. Bush (forgive the paraphrase here) that the president did the same thing on Wednesday that he did on Monday, no matter what happened on Tuesday. Now, I believe some of what the conservatives say - only some - but that certainly is madness.
