"Lichtman’s model has successfully predicted the winner of the popular vote in every presidential election from 1984 to present, with the exception of 2000. In the contested election of 2000, the system predicted the popular vote winner, although not actual winners. As a result in 2000, he predicted using his system that Gore would be the next president; Gore won the popular vote but lost the electoral college. In September 2016, the Keys forecast that Donald Trump would win the popular vote in the 2016 election, whereas he lost the popular vote, but won the electoral college."
I think you need to read his stuff more carefully.
But what do I know? It is just splitting hairs at this point.
I would agree Obama had no major foreign policy win in term 2. Cuba is not a major country and was trending that way anyway. It was a layup at best.
