Once the final voter casts their poll in a state and the polls shut, the method of showing the winner begins. That’s when Election Day turns into election evening, and every state begins reporting its vote totals.
Some states — like Florida, Georgia and North Carolina — report their vote shortly, whereas others like Arizona, Nevada and California sometimes take longer, upward of per week or two to tabulate most of their ballots. Within many states, the patterns of how votes are reported could make it troublesome to inform in the course of election evening who the winner goes to be in the long run.
For instance, vote returns can skew towards one occasion early in an evening as a result of solely a sure sort of vote is reported first — like when mail ballots are counted earlier than any in-person Election Day votes. These patterns can create what are typically known as “vote mirages.”

A vote mirage is when the present vote rely reveals a candidate getting the next proportion of the vote than they’ll in the end find yourself with within the last rely. Mirages might be “crimson” or “blue” relying on which occasion seems to be benefiting — however “seems” is the actually necessary factor right here, as a result of like some other mirage, a vote mirage is fleeting and doesn’t mirror the ultimate actuality.
The elements that produce a vote mirage
Generally talking, there are three elements that produce vote mirages: geography, vote mode and order of tabulation.
Mirages can emerge due to geographic variations within the counties that report extra shortly or extra slowly. It’s widespread for small, rural counties or precincts to report their tallies extra shortly than giant, city ones, as a result of the logistics of counting votes are easier when there are fewer ballots to deal with. As a end result, since voters in rural areas usually tend to be Republican than voters in city areas, a crimson mirage can occur when a state’s vote rely overrepresents rural areas at a sure level on election evening.
Virginia is an instance of a state that often has a geography-driven crimson mirage early on election evening. This is as a result of Fairfax County, a high-population suburb of Washington, D.C., the place Joe Biden acquired 70% of the vote in 2020, tends to be one of many final counties within the state to report most of its outcomes. Until Fairfax County has reported most or all of its votes, Donald Trump will possible have a statewide vote proportion that’s larger than his last statewide complete.
On election evening 2020, Fairfax County reported the outcomes from a majority of its ballots (practically 375,000 votes) at 11:43 p.m. ET. This single report triggered Trump’s statewide vote proportion to shrink in that second from 50.2% to 45.8%. (That’s near Trump’s last vote share in Virginia, 44%.)
Another issue that may trigger vote mirages is partisan variations by vote mode — mail ballots, early in-person votes, Election Day in-person votes, and so forth.
Many states and counties are inclined to report the outcomes of every mode one by one. This may cause vote mirages if one occasion is extra possible than the opposite to solid its votes utilizing a specific mode. This was the case in 2020, when Democrats voted extra by mail than Republicans, and Republicans have been more likely to indicate up on Election Day.
This distinction triggered a big blue mirage in North Carolina in 2020. In the primary hour after polls closed, most North Carolina counties had reported their mail and early in-person votes. Those votes have been closely Democratic, and at 8:18 p.m. ET, Biden was at 57.6% within the statewide vote rely. But over the subsequent three hours, the state reported its closely Republican Election Day votes, inflicting Biden’s vote proportion to shrink to his last quantity there, 48.6%.
The third issue that may produce vote mirages is extra sophisticated: variations within the order that particular modes of ballots are counted. This tends to be probably the most consequential in states and counties that report the outcomes of their mail ballots in small batches.
Many election workplaces are inclined to rely their mail ballots within the order that they have been acquired, that means that ballots returned by voters in mid-October will seem within the vote tallies sooner than these acquired on Election Day. This will produce a vote mirage if there are partisan variations between the earliest-returned mail ballots and the later-returned ones.
This is what occurred in Arizona in 2020. The mail ballots reported by Maricopa County (which accounts for 60% of the state’s voters) on election evening included these returned by voters by the weekend earlier than Election Day. This ended up producing a blue mirage, as a result of these earlier mail votes have been extra Democratic than the later ones.
The outcomes of the later-returned mail ballots have been reported within the days following Election Day. Because these late-arriving mail ballots have been closely pro-Republican, Donald Trump’s vote rely grew from 46.8% at 3 a.m. ET on election evening to his final vote share of 48.9% — simply shy of Biden’s 49.2%.
Interestingly, Arizona’s sample within the 2018 midterm election was the alternative. Late-arriving mail ballots have been far more closely pro-Democratic, and, as soon as they have been added, the Democrat, Kyrsten Sinema, went from trailing by 0.8 proportion factors on Election Night to profitable the election by 2 factors.
What to look at for by way of mirages in every state
The NBC News Decision Desk accounts for these mirages when deciding whether or not to undertaking the winner in a race. For instance, we’re much less prone to undertaking a Republican winner in a state if all of the remaining uncounted ballots are anticipated to come back from closely Democratic counties. Conversely, we’re much less prone to make a projection if the Democrat is forward however many of the uncounted ballots are anticipated to be strongly Republican, in-person Election Day votes.
We are additionally cautious about assuming that historic patterns will maintain in 2024, particularly on condition that the 2020 election was held throughout a pandemic, with voters extra prone to vote by mail and social distancing affecting how election officers tabulated the outcomes. This yr, the Trump marketing campaign has additionally inspired his supporters to vote early, which can have an effect on partisan variations between vote modes.
Here are particular particulars in regards to the mirages we have now seen in key swing states up to now — and what may occur on election evening this yr.
North Carolina: Most of the mail ballots will possible be reported first, inflicting a blue mirage. In a change for this yr’s election, in-person early ballots can’t be tabulated till after polls shut on Election Day. We count on the in-person early votes to start out coming in round 8 p.m. ET, a half-hour after polls shut within the state. But the vote percentages will shift towards Republicans as in-person Election Day votes get reported over the course of the night.
Georgia: Most counties will report their early in-person and mail ballots first, possible inflicting a blue mirage earlier than the statewide outcomes transfer towards Trump as Election Day votes are reported. After that, there could also be a small shift again towards the Democrats, because the late-arriving mail ballots are reported from giant metro Atlanta counties. Unlike 2020, Georgia counties should not allowed to pause their vote-counting course of till they’ve counted all ballots.
Pennsylvania: We count on the earliest-reported votes to be dominated by mail ballots, together with from closely Democratic Philadelphia and Allegheny counties, inflicting an early blue mirage. Then, as in-person Election Day votes are reported, the blue mirage will flip right into a crimson one, with the outcomes tipping extra Republican than we count on to see within the last margin. Finally these giant counties (notably Philadelphia) will proceed to rely and report their remaining mail ballots. This will possible shift the race again in Democrats’ route.
In 2020, the Pennsylvania outcomes at 3 a.m. ET on election evening have been about 7 proportion factors extra Republican than the ultimate end result. In the 2022 Senate election, the three a.m. crimson mirage was simply over 1 proportion level from the ultimate margin.
Michigan: We count on a slight crimson mirage in Michigan as smaller, extra pro-Republican localities report their votes. The complete vote rely will possible trickle upward as small locations report, and the scale of the mirage will shrink when giant, Democratic cities like Detroit, Grand Rapids and Ann Arbor report. This yr, Michigan voters can vote early in particular person for the primary time in a normal election, and clerks are actually permitted to preprocess their mail ballots, enabling quicker counting. Both of those modifications might trigger variations in vote reporting patterns in comparison with what we have now seen in earlier elections.
Wisconsin: In most Wisconsin municipalities, all modes of vote are reported collectively. This produces a slight crimson mirage, as a result of smaller, rural municipalities are inclined to report extra shortly.
A handful of huge municipalities, together with town of Milwaukee, tabulate their mail ballots centrally and report them individually from their Election Day votes. The state will expertise a crimson mirage till the closely Democratic mail ballots from most closely Democratic cities within the state are reported. At 4:42 a.m. ET on election evening 2020, Milwaukee reported that Biden had acquired 85% of its 168,000 mail ballots. This triggered Biden’s statewide complete to extend from 47.3% to 49.3%.
Arizona: In 2020, about 70% of the state’s votes — largely early in-person and early-arriving mail ballots — have been reported within the first hour after polls closed. This generated a statewide Biden lead of over 14 proportion factors in a state he in the end gained by 0.3 factors.
As Election Day votes have been reported within the subsequent few hours of election evening, the scale of the blue mirage shrunk to about 3.5 factors. It continued to shrink after Election Day because the pro-Trump, late-arriving mail ballots have been reported. In the 2022 Senate race, the Democrat was forward within the first hour by 19 factors and gained by 5. But within the 2018 Senate race, the sample labored in the other way, with the Republican forward by 3 factors early earlier than in the end shedding by 2 factors.
Nevada: Nevada will expertise a crimson mirage till Clark County (Las Vegas) experiences. In 2020, Clark’s first report got here 90 minutes after the primary county within the state had reported its votes. In 2022, this hole was solely 10 minutes. Then, the primary report in Clark might trigger a blue mirage, which can shrink as in-person Election Day votes are tabulated statewide.
Late-arriving mail ballots can be reported within the days after Election Day. In 2020, these ballots moved Biden’s lead from 0.6 proportion factors to a last results of 2.4 factors.
