It’s a tale of two electorates in the ABC News/Washington Post tracking poll, with shifts in intended turnout moving a large advantage for Hillary Clinton a week ago to a far tighter 2016 presidential race today.

From a 50-38 percent Clinton lead over Donald Trump in the tracking poll’s first four days, Oct. 20-23, it’s a 47-45 percent contest in the latest results. The movement has been in Trump’s favor, +7, while the -3 in Clinton’s support is not significant, given the sample size.
