Republican nominee Donald Trump gained 17 points in roughly two weeks, according to the Reuters online tracking poll.
On July 14, 2016, Trump was 15 points behind Democratic nominee Hillary Clinton 46.5 percent to 31.5 percent. However as of July 26, 2016, Trump closed that 15 point gap and is now up two points over Clinton, 40.2 percent to 38.5 percent.
The Reuters/IPSOS polling data was fairly consistent during the Republican primaries — keeping Trump in the lead from February through May, which proved to be accurate.
Additionally, IPSOS received a high polling accuracy score — an “A-” — from FiveThirtyEight.
