Kristol, a vocal critic of President Trump who serves as editor-at-large of the conservative Weekly Standard magazine, posted a Twitter poll asking if the president’s second oldest son was “too stupid to know he’s being anti-Semitic,” with the options “yes,” “no” and “not mutually exclusive.”

As of Wednesday afternoon, more than 16,000 people had voted in the poll, with “yes” and “not mutually exclusive” at 44 and 45 percent, respectively.
