The CBC's Presidential Poll Tracker gave Clinton a 3.4-point lead in national polls over Trump on election day. The assumption that the polls were wrong — massively wrong — has become part of the lore of the 2016 election. In the last Marist poll conducted before election day in 2016 , Clinton was losing the non-college graduate vote by 11 points. And the changes pollsters have made since 2016 make it difficult to compare polls in this campaign to polls in the previous campaign. Voters who disliked both Donald Trump and Hillary Clinton supported Trump in bigger numbers at the ballot box in 2016, according to exit polls.
