"Pew Research Center’s new national political survey finds that just 38% of registered voters who support Trump are very confident their vote will be accurately counted. Another 31% say they are somewhat confident, while 30% have little or no confidence their vote will be counted accurately.
Among Clinton supporters, 67% have a high degree of confidence that their vote will be counted accurately and 25% are somewhat confident. Just 7% have little or no confidence.
The gap between the two camps is about as large among those who express confidence in an accurate vote count nationally. Nearly half of Clinton supporters (49%) and just 11% of Trump supporters are highly confident that votes across the country will be counted accurately."
