Quoted from the Daily Mail article in the above posted link:
"It's worth noting that each time he buries one of the reforms of the man who sat before him at the "Resolute desk," Trump sounds more like a candidate than a president."
"I think that Obama understands that his legacy ultimately will be defined by how America reacts to Trump in the long term and how Trump's successors act," said Engel.
The fact that the voters felt so much disgust with his party that they preferred a guy with zero political experience to his given "successor" should be enough to tell the world how America felt about his "legacy".
