That's the percentage of African-American voters who picked Donald Trump over Hillary Clinton in the battleground states of Ohio and Pennsylvania, according to the latest NBC News/Wall Street Journal/Marist polls.
In Ohio, where the two candidates are tied, 11 percent of the 848 registered voters in the poll were African American, and they broke for Clinton, 88 percent to 0 percent.
And in Pennsylvania, where Clinton was ahead by nine points, 10 percent of the 829 voters are African American, and they went for Clinton, 91 percent to 0 percent.
The other NBC/WSJ/Marist poll, of Iowa, didn't have enough African-American voters for a statistically significant sample.
Among white voters in Ohio, Trump bested Clinton by 10 points, 43 percent to 33 percent.
But in Pennsylvania, they were tied here, 40 percent to 40 percent.
The NBC/WSJ/Marist polls were conducted July 5-10 of 822 registered voters in Iowa (which has a margin of error of plus-minus 3.4 percentage points), 848 registered voters in Ohio (plus-minus 3.4 percentage points) and 829 registered voters in Pennsylvania (plus-minus 3.4 percentage points). Percentages don't always add up to 100 because None, Other, and Unsure were possible answers.
