Go check out the pictures accompanying this NYT article on the Kennedy endorsement. Look at how Obama is mobbed by a multi-racial group of students treating him like a rock star and then Clinton operating comfortably behind a fence with everyone seated behind it.

The Kennedy endorsements are making bigger waves than I expected. I was surprised to see this Pittsburgh Post-Gazette editorial focusing on Caroline Kennedy’s op-ed. It was gushing in praise for what she wrote. I expect to see the editorial board to endorse Obama later in the year.

Ms. Kennedy doesn’t say it, but it is interesting that criticism of her father in the 1960 campaign turned to no small degree on his alleged lack of experience as a 43-year-old senator to prepare him for the presidency. That didn’t stop him from winning, or — as president — from leading us as a nation toward a bright future.

President Kennedy’s few years as president have been the benchmark for hope for Americans ever since. His daughter is saying that Mr. Obama could be that for us now in this time of grave need for brighter prospects.

The primaries are far from over — and Mr. Obama’s candidacy may yet be found wanting. But Ms. Kennedy has explained his appeal better than anyone else.
