In most of the core swing states, Joe Biden has maintained a stable — though not overwhelming — lead over Trump in polls over the past few months, continuing into the final week of the election. Some of the state polling averages have tightened slightly since the last debate, though Biden remains consistently ahead. In three live-interview polls of Florida all released on Thursday, Biden led Trump by between 3 and 5 points.
In some of the potentially decisive states, like Pennsylvania, the polls would have to be wrong to a significant greater — greater than the errors in 2016 — for Trump to win. The latest polling averages show Biden with a 5-point lead…
In 2016, the larger-than-usual share of voters who said, even in the late stages of the campaign, that they were undecided or preferred a third-party candidate was a flashing warning light that Hillary Clinton’s lead was not secure. Clinton was not well-liked, even if she was running against a historically disliked opponent. And Trump was garnering momentum in the closing two weeks of the race.
None of those is happening this year: There are generally fewer undecideds in the polls. Biden is viewed favorably by a narrow majority of voters in the country. And surveys conducted since the debate last week have not showed as large of an uptick for Trump.
