And Reagan in '88 and Clinton in '00. On this, he's probably right.
Hillary's loss came in part to her inability to hold the Obama coalition together. Listening to Obama speak during this twilight of his administration, he comes across as a man less upset with Trump for rolling up his sleeves and winning as he is profoundly disgusted with the Clintons, the DNC, Podesta, DWS, and the rest of them for their corruption, arrogance, tone-deafness, and hubris in running a disastrously lazy campaign that will ensure everything he worked for this past eight years will have been for naught.
I disagree. Obama ran against RINOs who were afraid to attack him because he is black and they shared many of his beliefs. Biden said of one of the debates, he did not know if Romney was debating him or endorsing him. If Trump ran against him and his lacky media it would have been different. Questions would be asked like, “Where were you on the night of Benghazi?”
