WGBH's Emily Rooney, Margery Eagan and Adam Reilly talk the state of the race, the why of our own governor's endorsement and whether “Robot Rubio” is cooked.

Reilly and Eagan agreed that Baker's endorsement of Chris Christie doesn't mean much. "I don't think it's a big deal," said Eagen.

"Baker had to pick someone," said Reilly. And Christie was a safe choice due to his low standing in the polls. 

They all agreed that Rubio's debate performance was poor. "[Marco Rubio] is the only candidate that was in the top tier who started trending downward," said Rooney.
