Former Democratic Sen. Claire McCaskill said Monday that Americans weren't "smart enough" to keep President Donald Trump away from the White House. "And yes, The Wall Street Journal may say America is smart enough to know better. I will tell The Wall Street Journal this: America, I believe, clearly was not smart enough to keep this guy from the White House. He is causing confusion and uncertainty in a segment of our economy that desperately needs certainty. And by doing that, he is going to get higher prices. And that’s when America will finally get smart, but they’re not smart now
