"We need to get rid of caucuses," said Melissa Whitener, a waitress from Conneaut, Penn., who traveled to lobby the Democratic National Committee as it prepared its party platform.

"Caucuses are inherently unfair," she said. "I work in a restaurant. I can't take off a whole shift to go sit in a caucus. We need to all be on the same primary system. Why should 2,000 people in Iowa have the same say as 2 million in Pennsylvania?"

Why, indeed?
