Hillary Clinton plans to attack Donald Trump's fitness to handle economy

Hillary Clinton plans to say that Donald Trump is "temperamentally unfit" to handle the U.S. economy.

The presumptive Democratic nominee told USA Today in an interview that she plans to make "a similar case on the economy that I did on foreign policy: that Donald Trump is erratic and temperamentally unfit to be responsible for the world's largest economy."

Clinton said she will make her argument in a speech in Columbus, Ohio next Wednesday. She will pledge to end the carried-interest tax loophole for wealthy Americans by using executive action if Congress doesn't take action.

She told USA Today that Trump's proposal would lower tax rates for hedge fund and private equity managers by creating a lower 15 percent bracket.

"He's either completely incoherent or he hasn't thought one bit about his plan," Clinton said.

Clinton also declined to weigh in on the future of Democratic National Committee chairman Debbie Wasserman Schultz, after Bernie Sanders called for her replacement. But Clinton did praise the chair for her work against Trump.

"I've seen how committed she is to making sure Donald Trump is not the president," Clinton said about Wasserman Schultz. "I've not heard any conversations in the party about changes."

A new CBS News poll released Thursday found 43 percent of registered voters back Clinton for president compared to 37 percent who support Trump.
