The Significance of Senatorial Endorsements

Brian Beutler makes some keen observations about the meaning behind the endorsements by senators of Clinton and Obama. I particularly like this observation about Ted Kennedy's endorsement:

Kennedy chairs the Committee on Health, Education, Labor, and Pensions atop both Clinton and Obama. He is, at the same time, the senior Democrat on the Armed Services Committee, which is the very committee that has supposedly served as Clinton's home school for acquiring her widely praised military expertise. He is, in other words, not just the nation's most trusted and revered Democrat, but also, coincidentally, the one who's had the greatest opportunity to see the young candidates at work. And he came away supporting Obama.
