A poll conducted by SSRS of 15 battleground states found former Vice President Joe Biden trailing President Trump.
The same poll, conducted for CNN, found Biden ahead of Trump nationally, but losing in the 15 states that might decide the vote in the Electoral College.
The poll did not include different surveys of each of the 15 states, but surveyed 583 people across 15 states that were decided by 8 points or fewer in 2016. The margin for the battleground states alone was 5.3 points.
The 15 states are Arizona, Colorado, Florida, Georgia, Maine, Michigan, Minnesota, Nevada, New Hampshire, New Mexico, North Carolina, Ohio, Pennsylvania, Virginia and Wisconsin.
Trump lead Biden in the poll across those states 52 percent to 45 percent.
Nationally, the poll found Biden leads Trump 51 percent to 46 percent.
The poll was conducted May 7-10 among a random national sample of 1,112 adults, including 1,001 registered voters. The full nationwide survey had a margin of error of 3.7 points.
The poll found Trump with a slight edge among independents, at 50 percent to 46 percent. It found Biden leads 55 percent to 41 percent among women and 69 percent to 26 percent among people of color, while Trump leads with white people 55 percent to 43 percent.
