Chelsea Clinton is a very public figure. So why does she still feel so distant?

Why do people care about Chelsea Clinton? Five years ago, all she wanted was a quiet wedding (of about 500 people). It required police barricades and a no-fly zone. Reporters chased her guests through the streets while savvy locals hawked Marc-and-Chelsea T-shirts and "I Do" pizzas. The Vera Wang dress, the gluten-free cake, the uninformed estimates of the event's exorbitant cost -- headlines for days.
