Clinton has an even wider advantage on the issue of presidential temperament. Significantly more voters say Clinton has the right temperament for the job (59%) than say the same about Trump (33%).

Trump's former accountant Jack Mitnick, who was in charge of his tax returns from the 1960's to 1996, was on TV this week. He said Trump doesn't understand the tax code and had nothing to do with preparing his return.

"As far as I know, and that only goes through late '96, he didn't understand the code," said Jack Mitnick, a former tax adviser for Trump, in an interview with NBC's TODAY. "Nor would he have had the time and the patience to learn the provisions. That's a lifetime of experience."

He said Ivana was more interested than Trump in the topic. All Trump cared about was the bottom line.

Mitnick, however, told the TODAY show Tuesday that Trump was "not at all" involved in the 1995 filing. "He was interested in the bottom line, not the detail," Mitnick said. "Staff under my supervision did his returns - he had no involvement in the preparation."

So did Trump use business losses to offset his personal tax liability? Mitnick won't say -- he says you have to draw your own conclusions, but everything Trump did was legal in the tax code. He also warned against assuming the loss of $915 million was generated in 1995 -- he said you can't determine that from the one page released by the New York Times.

So much for the "genius" of Trump.
