The Obama campaign is going to seriously escalate the "when did Mitt leave Bain" question. There is no down side for the Obama people. Mitt signed SEC documents saying he was president and CEO until 2002, not 1999; the difference being Bain's outsourcing of job and lading companies with debt then bankrupting them for profit while Mitt was directing the company after he supposedly left in 1999 as he claims.
This is going to destroy Romney. Obama is going to win because of this.
