“I will tell you, I’m mystified as to why she can’t get to those 52–53 percent numbers in some of these states given the disadvantages we’re handed every day,” Kellyanne Conway told host Anderson Cooper on CNN’s “360” late Tuesday.

“She has so many advantages. She has endless money. She has a lot of the media. She has a very popular president and first lady out there campaigning for her.”

Conway said Trump, the Republican nominee, remains competitive in the White House race because he is not an establishment politician like Clinton.

“I don’t feel sorry for us,” she said of Trump’s bid. "We’re going to win because people love a comeback story.

“The one thing Donald Trump has that she does not is the mantle of change and disruptor and Washington outsider. Successful businessman versus typical politician.”

Conway added grassroots support for Trump is hard to measure before Election Day.

“Will the people who stood for four hours in the rain — today in Colorado they were overflow — you know they’re going to vote. And I think they’re not all counted in the polls.”
