Well, even we didn’t see this coming.

One of the greatest untold stories of the fierce 2012 Republican primary is out today thanks to Businessweek’s Joshua Greene.

Newt Gingrich and Rick Santorum nearly ran together. The two negotiated over forming a ‘unity ticket’ aimed at shoring up conservative support, but negotiations broke down and left Romney with the nomination.

‘The way it was going to work was you join forces, one person is president, one person is VP, you lock it up then and you create this wave of excitement,” Greene said on Morning Joe. “It would be the final push needed to topple Romney.”

“The appeal of a Unity Ticket was strength in numbers,” Kellyanne Conway, Gingrich’s pollster, says in Businessweek. “The big question was, who was going to unify with whom? Who was going to be the sheriff and who was going to be the deputy?”

"As Mitt Romney struggled in the weeks leading up to the Michigan primary, Newt Gingrich and Rick Santorum nearly agreed to form a joint 'Unity Ticket'," writes Bloomberg Businessweek's Josh Green. Green joins Morning Joe to discuss this tale of "ego and intrigue."
