To determine whether voters think Trump abused his powers, FiveThirtyEight went back and averaged eight high-quality polls from late September to late November testing the abuse of power question.
We found that 54 percent of Americans believe Trump either abused his power or acted in his own self-interest, while 39 percent said he had not. That’s basically in line with the share of Americans who believe Trump committed an impeachable offense, according to our own polling with Ipsos.
