WASHINGTON (AP) — In a remarkable slap at their own presidential nominee, Republicans are running a TV ad in Chicago that touts a GOP congressman's independence by showing him saying Donald Trump "has disqualified himself." Several GOP ads have promoted congressional candidates as curbs against the policies that Democrat Hillary Clinton would favor as president — an implicit acknowledgment that Trump could well lose. The figures were provided by people with access to political advertising data who spoke on condition of anonymity because they were not authorized to discuss the information publicly.
