Obama's entire presidency is based on deals with the Clintons. First Obama had to get Hillary to quit during the 2008 primaries and convention. Hillary could've contested the primaries by having allegations of harassment and intimidation been investigated and could've taken the 2008 nomination to a floor fight at the convention. So Obama gave Hillary the Secretary Of State job to shut her up. Hillary loyal to the party took the deal also seeing it as a resume builder for running as the first serious women presidential candidate.
Then after muddling through his first term not solving economic problems or prosecuting many of the culprits he was looking like a democratic dud. Clinton support probably swung the election in his favor with Clinton salvaging many moderate and undecided voters.
Obama owes both terms to the Clintons. Hillary is still a possible candidate because of her 'dealings' as well. Bengazhi might kill it but senator AND Secretary of State might have been the resume saver for the first women president.
