"Fifty five percent flatly rule out voting for [Trump] him next year," the poll found.
One in three likely voters said they would "definitely" support Trump, while another 14 percent have not made their choice yet.
"While more than half say they’ll definitely not support Trump, 42 percent of Americans overall, and 45 percent of registered voters, say they would at least consider him for a second term," the poll found.
Trump's stances on economy, international trade and immigration make voters more likely to support him, the poll found. On the other hand, his positions on issues such as immigration, health care, international trade and Special Counsel Robert Mueller report are among the major reasons voters could vote against Trump, the poll found.
The ABC News/Washington Post poll was conducted by phone between April 22 and 25, surveying 1,001 adults nationwide.
