Mrs Clinton's lead grew as Americans soured on Mr Trump's bellicose response.A similar scenario unfolded in June following the Orlando nightclub shootings.

This time Mr Trump has been more measured, offering only condolences on Twitter. He did call the New York incident a "bombing" before official confirmation and said the US needed to "get tough", but that was hardly comparable to his jarring comments on Orlando.This time Mr Trump has been more measured, offering only condolences on Twitter.

With the race tight once again and the first TV debate just over a week away, both candidates are under intense pressure to display their leadership qualities. Saturday's "nightmare scenario" was another test - and it probably won't be the last.With the race tight once again and the first TV debate just over a week away, both candidates are under intense pressure to display their leadership qualities.
