Your Questions -- The YouTube presidential debate
Democratic presidential candidates will square off tonight in a debate with a twist: this is the first time questions will be posed by members of the public via Internet videos. The two-hour debate begins at 7 p.m. and is sponsored by CNN, YouTube, and Google. CNN editors will select questions from thousands of personal videos uploaded to YouTube over the last few months. We've assembled some of the questions asked by Massachusetts residents.
