These two issues are true in the case of the presidential race: Polls present Vice President Kamala Harris and former President Donald Trump successfully tied.
And shutting the polls doesn't essentially imply there might be an in depth outcome.
This will likely appear contradictory, however the reality is that we’re just one very regular survey error for any of the candidates to get one decisive victoryparticularly within the Electoral School.
This can be a level from my colleague New York OccasionsNate Cohn has talked about it often in his race updates over the previous few weeks.
However it’s value repeating, as a result of an unbalanced outcome when there’s an expectation of very narrow margins it may additional promote distrust within the polls and within the electoral course of itself.
“It may very well be an in depth election within the well-liked vote, and somebody might recover from 315 Electoral School votes, which received't look shut,” stated Lee Miringoff, director of the Public Opinion Institute at Marist School.
The names of Democratic presidential and vice presidential nominee Kamala Harris, Democratic vice presidential nominee Tim Walz, Republican presidential nominee and former U.S. president Donald Trump, and Republican vice presidential nominee JD Vance seem on a poll official for the 2024 U.S. presidential election on Election Day in Manhattan, New York, U.S., November 5, 2024.

Since 1998, election polls in presidential, Home, Senate, and gubernatorial races have differed from the ultimate vote depend by a mean of 6 proportion factorsin response to an evaluation by FiveThirtyEight.
However within the 2022 midterm elections, the typical error was four.eight factors, making it essentially the most correct voting cycle within the final quarter century.
If the polls had been fallacious this yr, both manner, by the identical margin, the profitable candidate would win a decisive victory.
Based mostly on the place Monday's polling averages stand, if polls underperform Harris by four.eight factors in every of the seven swing states, she would win all of them and a complete of 319 electoral votes, in comparison with simply 219 for Trump.
If the identical polls underperform Trump by the identical margin, he would win each state within the battleground state, for a complete of 312 electoral votes.
(These calculations assume that Harris and Trump every win the opposite states during which they’re the favourite.)
It’s potential that surveys make no mistake all in the identical route, or to that extent.
However even a yr of traditionally correct voting might imply that both candidate sweeps many of the battleground states:
Arizona, Georgia, Michigan, Nevada, North Carolina, Pennsylvania and Wisconsin.
Pre-election polls have a specific amount of error inbuilt, partly due to the voting course of itself, however largely as a result of they need to guess who will truly end up to vote, to match the pattern they’ve with that inhabitants of voters.
Different public opinion polls that target non-political points do not need to take care of this problem.
“For the reason that instruments pollsters need to predict turnout are fairly restricted (acknowledged voting intention, curiosity within the election, the perceived significance of the resultparticipation in earlier elections), they’ll all make the identical errors if these instruments aren't as helpful in a specific election,” stated Scott Keeter, senior polling adviser on the Pew Analysis Heart.
After all, who exhibits as much as vote makes a giant distinction in who wins.
Trump's greatest lead in any key state now could be in Arizona, the place polling averages present him forward by three factorsso even a 2 or three proportion level error might imply a giant win for both candidate.
A part of it is because polls are likely to err in the identical route in a given election cycle (although not at all times), and battleground states which might be demographically related are likely to vote the identical manner (though once more, not at all times).
Consequently, if the polls are fallacious by a small margin, however in the identical “tackle” (whether or not Trump's understatement or Harris' understatement), it might imply the distinction between one candidate or one other, knocking over swing states like dominoes.
None of this implies we'll essentially have a knockout victory on Election Day; there’s nonetheless the very actual risk that it will likely be an in depth race that might be determined by just a few hundred votes in a single state.
However understanding that these are potentialities which might be throughout the polls' regular vary of error might help buffer a number of the shocks when the outcomes are lastly tallied.
