One of the most common stats trotted out in this presidential campaign is that presumptive Republican nominee Donald Trump and Democratic nominee Hillary Clinton are the most unpopular candidates in modern history, with more voters saying they have an unfavorable view of the candidates than a favorable one. Indeed, 23 percent of American voters we polled have an unfavorable view of both Clinton and Trump.

At Morning Consult, we wanted to find out why. So we asked voters who had an unfavorable view of either Trump or Clinton to pick the top two reasons they dislike the candidate from a list of more than a dozen negative attributes.

What we found is that the main drivers of Clinton and Trump’s unfavorable numbers play in to larger campaign narratives: Voters think Trump is racist, and Clinton is untrustworthy. Even more importantly, both are underwater in almost every state.

The results below provide an in-depth look into the study and the challenges ahead for both campaigns. You can see more about our methodology below.
