warrenJust a few days after Chelsea Clinton announced at the Lower Eastside Girls Club that she’ll soon make Bill & Hill grandparents, Liberal Dream Week continues with a pair of progressive pols putting in appearances at Barnes & Noble Union Square.

Tonight at 7 p.m., five-time presidential candidate Ralph Nader will promote his new book, Unstoppable: The Emerging Left-Right Alliance to Dismantle the Corporate State. A bookseller at the store said Nader will most likely give a reading and sign copies.

Twenty-four hours later, Massachusetts senator Elizabeth Warren will participate in a Q&A about her new book, A Fighting Chance, which is a combination of memoir and message. Priority seating begins at 5 p.m. for those who purchase copies. All books will be pre-signed by Senator Warren.
