If Chelsea keeps giving opinions, regardless of how warped they are, she becomes a public figure and a legitimet target for the media.

[Azzurri]

Chelsea is an example (as are her parents) of someone educated beyond their intelligence. She "expounded" on Bush's tax cut as building were falling around her. Expounded is one of those words used by pontificators who are trying to make themselves sound intelligent...especially in the context that she used the word.
