Softening

Rich Lowry, at the friggin' National Review:

If Hillary can’t win the nomination—and it’s clearly very, very hard for her—she’s basically a stalking horse for McCain. She’s preparing the demographic ground for McCain, by getting white working-class Democrats used to (if you will) not voting for Obama. And she’s softening Obama up for McCain, prodding at and exposing her fellow Democrats’ weaknesses.

Certainly, it's her "right" to keep fighting as long as she wants.

Her actions and her choices are, of course, her legacy.
