What debates?
There’s only one declared candidate. I supposed, considering her health that she might mutter opposing viewpoints back and forth.
At least four: Cankles, Bernie Sanders, Jim Webb and O'Malley. And likely Joe Biden.
Official ‘major’ declared: Hillary Clinton, Vermont Sen. Bernie Sanders, former Maryland Gov. Martin O’Malley, former Virginia Sen. Jim Webb, and former Rhode Island Gov. Lincoln Chafee, not to mention the likely Biden.
