When words come out of politician’s mouth that are linguistically incorrect, people see it reflecting their intelligence. Sarah Palin was called out for “refudiate,” which seemed to combine refute and repudiate. One favourite Bushism was “misunderestimate.”
Donald Trump himself has an idiosyncratic speaking style that relies on simple words and phrases, which worked for him in the primaries but may be coming up short for him now.
