It will be one of the final chances for Barbara Buono to get back in the gubernatorial election. Gov. Chris Christie and Buono will face off on Tuesday in the first of two debates. Christie has about a 20 point lead in the polls. The debate will begin at 7 p.m. and will be televised on CBS. Buono has had a hard time gaining traction in this campaign, especially with a lot less money to spend than Christie.
