How does early voting affect election outcomes?

Early voting itself does not systematically advantage either party — it shifts when votes are cast, not necessarily who votes or for whom. However, the partisan composition of early voters has become an important strategic factor. Democrats have historically led early in-person voting in competitive states, while Republicans dominated Election Day turnout. This created the "blue shift" — results looking better for Democrats on election night as early ballots counted first swung toward them in some states. By 2024, Republicans had significantly closed the early voting gap through organized GOTV efforts, and in many states Republicans led early voting totals heading into Election Day.

Which states have restricted early voting in recent years?

Since 2020, several Republican-controlled states have restricted early voting or tightened rules around it. Georgia's 2021 election law (SB 202) reduced the early voting period for runoffs, banned mobile voting units, and restricted Sunday voting hours — provisions critics called an attack on "Souls to the Polls" drives in Black churches. Iowa reduced its early voting period from 29 days to 20 days in 2021. Florida eliminated the collection of drop boxes except during supervised hours. Texas banned 24-hour voting sites used in Harris County (Houston). Supporters of the restrictions argued they standardized procedures and reduced confusion; opponents argued they targeted methods disproportionately used by Democratic and minority voters.

Q: What is early voting?

Early voting allows registered voters to cast their ballots in person at designated polling locations before Election Day, typically during a window of one to three weeks before the election. As of 2024, 47 states and the District of Columbia offer some form of early in-person voting. Three states — Alabama, Mississippi, and New Hampshire — do not have traditional early voting, though all states offer absentee voting by mail. Early voting periods range from 4 days (several Southern states) to 46 days (Minnesota's in-person absentee starts earlier than most). Over 100 million ballots were cast before Election Day in the 2024 presidential election, representing approximately two-thirds of all votes.

Key Findings

Early voting is available in 48 states and DC — with most states allowing in-person early voting for 1-4 weeks before Election Day.
45% of ballots in the 2020 election were cast by mail — a historic high driven by COVID-19; the share has moderated since but remains well above pre-pandemic levels.
Early voting has been restricted in several red states since 2020 — including Georgia, Texas, and Iowa — limiting hours and drop-box availability in ways that critics argue disproportionately affect Democratic voters.
Democratic voters disproportionately use early and mail voting while Republican voters have been encouraged to vote on Election Day — creating partisan 'red shifts' in election results as Election Day votes are counted last.

Early Voting and Campaign Strategy

The Democratic Early Vote Machine

For years, Democrats built their GOTV strategy around early voting: "bank" reliable votes before Election Day to reduce the pressure of turnout on a single day. Organized labor, Black church networks ("Souls to the Polls" drives), and campus organizing made early voting a Democratic structural advantage in swing states. In 2020, Biden won Pennsylvania primarily on early votes; Trump won Election Day votes by a large margin but lost the state.

The Republican Counter-Push

After Trump's 2020 attacks on mail voting caused many Republicans to skip early voting entirely (a self-inflicted disadvantage), the GOP spent 2022-2024 reversing course. Republican state parties, led by the RNC's "Bank Your Vote" program, invested heavily in early vote turnout operations. By 2024, in many Sun Belt states Republicans matched or exceeded Democratic early vote totals — showing that early voting can be a Republican tool when the party chooses to use it.

The "Blue Shift" and Counting Order

In some states, early ballots are counted first; in others, they are counted last. Pennsylvania law did not allow early ballot processing until Election Day morning — producing a dramatic "blue shift" as early (Democratic) ballots were added after Election Day votes were reported. States that allow pre-canvassing of mail ballots (Florida, Arizona) produce faster, more complete results. The counting order debate has become politically charged because it affects the narrative arc of election night reporting.

Frequently Asked Questions

Does early voting increase overall turnout?

The research is mixed. Most studies find early voting shifts when votes are cast rather than significantly expanding who votes. The most comprehensive review (Gronke et al.) found early voting increases turnout by roughly 2-4 points in low-salience elections (primaries, off-year local races) but has a smaller or negligible effect in high-salience presidential elections where motivated voters would have voted anyway. The exception is same-day registration paired with early voting, which consistently shows larger turnout gains by removing registration as a barrier.

Can you change your vote after casting an early ballot?

In most states, no. Once an early ballot is cast, it is locked. A small number of states — including Wisconsin, Michigan, and Minnesota — allow voters who have submitted an absentee ballot to withdraw it and vote in person instead, but the rules and deadlines vary. In-person early votes are generally treated identically to Election Day votes and cannot be revoked. Voters who change their minds after early voting should contact their county election office immediately to understand their options, if any.

What is the difference between early voting and absentee voting?

Early voting refers to casting a ballot in person at an official polling location before Election Day. Absentee voting (also called mail voting or vote-by-mail) involves receiving a ballot by mail, completing it at home, and returning it by mail or at a drop box. In states with "no-excuse" absentee voting, any registered voters can request a mail ballot without giving a reason. Some states use "absentee" to describe both processes, which creates confusion. Both methods allow voting before Election Day, but they involve different processes, deadlines, and administrative procedures.
