Later, he became the veep candidate and was against trumpeted as a man of convictions and integrity. Within days of getting the nomination, he flip-flopped on virtually every issue he had ever supported (school vouchers, etc.) that deviated in any way from the standard left-wing, big government, nanny-state liberalism that rules the Democratic Party. His honesty and integrity proved to be about as solid and deep as that of the townspeople in Mark Twain's great story, "The Man Who Corrupted Hadleyberg." All it took was the very first hint of temptation, and all their much-ballyhooed honesty was tossed overboard for personal gain.
You have to earn a reputation for integrity, you can't just have it bestowed on you by the media, and Lieberman proved by his words and deeds that he's just another hypocritical phony. So whatever he says in the future, disregard it. It's probably just whatever he thinks he needs to say to advance his career. I had enough of that from 1992 to 2000.
