Democrat Hillary Clinton led Republican Donald Trump by more than 5 percentage points in the Reuters/Ipsos tracking poll released on Friday, little changed in weeks as the US presidential campaign wobbles into the heart of summer. Since July 28, Clinton's daily support among likely voters in the poll has hovered between a low of 41 and a high of 44 percentage points. She was at 41 percentage points on Thursday, down slightly this week. Among registered voters, Clinton was ahead by 9 points on Thursday, 42 to 33.
