Clive Crook: Why so many people still support Donald Trump

A week ago I expressed the hope that President Donald Trump’s lamentable performance after the protests in Charlottesville, Virginia, would hurt his standing in the polls. This didn’t happen. If there was a blip, it was in the other direction. I’d be pleased if Trump’s regrettable decision to pardon former sheriff Joe Arpaio dented his popularity, too, but I’m not holding my breath.
