Trump's secret weapon is Ivanka

“She’s seen much differently than her father — she certainly has a classier, more reasoned reputation, and she’s beloved by a lot of the people her father is not beloved by,” said Robert Thompson, a Syracuse University communications professor…

“I think Ivanka Trump has been Donald Trump’s best surrogate,” said Doug Heye, a former Republican National Committee aide who doesn’t support Trump.

“Unlike her father, she always appears poised and thoughtful, so I’m not surprised that she has such a prominent role in the campaign and the convention.”…

Her active role in his campaign, Heye said, helps to portray the candidate as a “good parent,” which could help his appeal.

“Whatever else is said about Trump by people who don’t support him, of which I am obviously one, she and his sons speak to the fact that he’s raised a good family, and that’s obviously an asset,” he said.
