“I think you’ve got a guy who is getting very, very nervous,” he told host George Stephanopoulos on ABC’s “This Week.”

“I understand that, because the last national poll had us 18 points ahead of him. Some state polls had us even more ahead of him.”

Sanders argued that Trump’s past remarks offer him plenty of ammunition should they battle for voters next November.

“This is a man who is dividing up his country in very serious ways, frightening ways,” the Democratic presidential contender said.

“I think what we are seeing in the Trump campaign is not only racist attacks, but what you’re seeing is attacks on Muslims, on women [and] on veterans,” Sanders added.
