For a president who has governed “by tweet and circus,” a potential global health crisis that blunts economic growth could expose one of Trump’s main weaknesses as he prepares to face voters in November, said Russell Riley, a presidential historian at the University of Virginia’s Miller Center. “Having hollowed out the senior leadership of so many departments of the government — especially in the scientific community — he is now in desperate need of professional guidance among people he has abused for three years,” Riley said. “If the markets continue to drop and the medical news gets very bad, then this president is singularly ill-prepared to deal with it in a rational manner.”
