US President Barack Obama's former campaign manager David Plouffe labels Republican presidential nominee Donald Trump a “psychopath” who meets the clinical definition of the personality disorder.
In an interview with NBC News, Plouffe was challenged for not being qualified to call Trump a psychopath, so he went on to list symptoms associated with the disorder he attributed to Trump: “grandiose notion of self-worth, pathological lying, lack of empathy and remorse.”
Plouffe is certain that Democratic presidential nominee Hillary Clinton will win as she has guaranteed 269 electoral votes, including those from Virginia and Colorado.
"There's maybe a 20 percent chance it's close — 2 or 3 points; I think it's likely going to be a landslide," he said.

Obama has also been a staunch critic of Trump during his remaining time in office.
“The Republican nominee is unfit to serve as president,” he said during a press conference in the White House early this month.
Obama said Trump “doesn’t have the judgment, the temperament, the understanding to occupy the most powerful position in the world.”
Clinton and Trump have both been undermining each other throughout their campaigns in the race to become president.
Trump recently said that Clinton “lacks the mental and physical stamina” to run the country.
Clinton has also taken a jab at Trump, saying he is fueling America’s “radical fringe” with racist rhetoric.
Americans will get to cast their votes for the United States presidential election on Tuesday, November 8, 2016.
