Help with the name of a Book

Hoping one of you spy masters can help out. All I remember about the book was that it's a spy or crime thriller. It features a modern day descendant of the Kennedy family running for Office, and has a parallel story with two teenagers that want to kill him. It all culminates in a rally for him, where the teens are there, as well as a secret agent charged with tracking them down. I believe the ending is ---- SPOILER ----- (the teenagers successfully kill the Kennedy politician, and then the secret agent kills them both)

It doesn't sound like much, but if anyone has any idea, i would greatly appreciate it!

Any idea of the author's name or when it was published? Without that, it sounds like an impossible task. There's no copyright privilege on titles. A Google search MIGHT turn up something, but that's a long shot.

I think it's a book from 2004, 2005. And no idea about the author. I tried searching for it on google using books that featured fictional members of the Kennedy family, but to no avail. Just hoping someone read the book and recognizes the plot I guess.
