Polls 17 months out did not predict the outcome of the 2016 election and they won’t predict the outcome of 2020, either:

Almost all of the polls in 2016 declared that Hillary Clinton would most certainly win the election. But they turned out not to be true. Trump won the Electoral College in 2016, not Clinton, 300 to 227, in spite of the state-by-state polls and head-to-head matchup polls. Given Clinton’s favored status, it was one of the greatest upsets in American political history. Now, early in the process, polls show Democrats have an early advantage in 2020. Could it be happening again?
