Robert Scheer in The Nation:
Unable to move with his brothers' intellectual alacrity, sometimes plodding in impromptu expression but smooth and skillful while reading from a script, the youngest Kennedy made up for his shortcomings early in his Senate career by resolutely working the substance of issues. His principled determination, plus his capacity to truly care about the real-world outcomes of legislation for ordinary people rather than its impact on his or anyone else's election, became his signature qualities as a lawmaker. But for those same reasons, he also wanted legislation passed, and his ability to work with the opposition, as he did three years ago with John McCain on immigration reform, now grants him a legacy as one of the nation's great senators.
Oddly enough, for one born into such immense familial expectations, he was a surprisingly accessible and down-to-earth politician in the eyes of most journalists who covered him. I think of him as always authentic and never oily. As opposed to most politicians, the offstage Ted Kennedy was the more appealing one.
Although he excelled as an orator, never more so than delivering the speech that Bob Shrum crafted for him at the 1980 Democratic Convention but which was informed by Kennedy's own deeply felt passion, it was in his less choreographed moments that he was at his best.
