Obama and Hillary Clinton will 'absolutely' hug it out

(CNN) – The book tour to rival all book tours continues on Martha's Vineyard, where Hillary Clinton is signing copies of her autobiography, "Hard Choices."

It's turning out to be a big week on the island, and tonight will be the main event. Clinton told reporters Wednesday she "absolutely" looks forward to hugging it out with the President at a party tonight hosted by a mutual friend.

This anticipated Obama-Clinton embrace is somehow one of the biggest stories in politics right now.

So why does anyone care about a pat on the back between two self-described pals? Because after using the word "failure" in her description of the President's foreign policy in Syria, the presumed 2016 candidate Clinton is now playing a dangerous political game, pulling close a President who's approval ratings are flatlining at all time lows, just as she's getting set, by all estimations, to push herself away from his policies.

This Obama-Clinton rift "was inevitable," says CNN analyst and Politco writer Maggie Haberman. She  joins CNN's "The Lead with Jake Tapper" to discuss.
