Tom Schaller at FiveThirtyEight.com wrote about the big names that were in the U.S. Senate when Senator Ted Kennedy began his career there:

Last night Ted Kennedy left the Senate for good as its liberal lion. But his point of arrival tells us a lot about him, too, for he was trained by, learned from and found great company among a group of pretty amazing senators in Washington when he arrived as a young cub on the scene almost 47 years ago.
