OK I've found a clean copy. It is from an interview with Obama. Not sure when the interview took place but the report in Bloomberg's magazine, is dated 17th July. Here is the relevant section:
"
Barack Obama has said he believes he would have won a third term in office were he eligible to run in the 2016 presidential election, while also casting a skeptical eye at the UK Labour party under Jeremy Corbyn’s leadership.In a wide-ranging interview with former aide David Axelrod, the outgoing president expressed his belief that he could have won re-election in 2016, based on his view that most Americans still subscribed to his progressive vision and ideals.
“I am confident in this vision because I’m confident that if I had run again and articulated it, I think I could’ve mobilized a majority of the American people to rally behind it,” Obama said on Axelrod’s CNN podcast.
The outgoing president summarized this progressive American spirit as one that “manifests itself in communities all across the country”.“We see it in this younger generation that is smarter, more tolerant, more innovative, more creative, more entrepreneurial, would not even think about, you know, discriminating against somebody for example because of their sexual orientation.”
Ultimately, Obama did not think the election represented a sea change in American politics or a repudiation of his administration, insisting that “the culture actually did shift, that the majority does buy into the notion of one America that is tolerant and diverse and open and full of energy and dynamism”.
To an extent, this was reflected in the final outcome of the election, where Hillary Clinton won the popular vote by nearly 3m votes."
Needless to say, this does NOT say Obama thinks he should have been entitled to a 3rd term, at all. Just that, if he had been, he thinks he could have won it.
