Barack Obama’s campaign against one political dynasty (the Clintons) is endorsed from the descendant of another one (Caroline Kennedy).

Why do we care again?

Update 1/28 10:06 AM: On the other hand, today’s endorsement from Ted Kennedy is a much bigger deal. In particular, as TNR’s Jonathan Cohn and a commenter below note, it could help Obama with Latinos and working class whites.

Update 1/28 2:23 PM: Josh Marshall offers a similar take:

If the issue is dynasticism in politics, I guess there’s some measure of irony in the group endorsement I’m now listening to from the Kennedy family.
