1840s

In the 1844 United States presidential election in Louisiana, Democrat James K. Polk won over Whig Henry Clay by 699 votes. The victory was due to Polk's fraudulent 990-vote margin in Plaquemines Parish, where he obtained 1,007 votes compared to just 17 for Clay.

The Louisiana State Legislature voted to invalidate the state's electoral votes as a result.^[16]
In the 1868 United States presidential election in New York, Tammany Hall machine boss William M.

1920s

In the 1926 United States Senate election in Pennsylvania, there was tampering of ballots that affected the vote count in favor of William Scott Vare against his opponent William B. Wilson. While the fraudulent ballots were not greater than the margin of victory, Vare was ultimately not seated by Congress due to campaign finance improprieties.^[40]

1930s

In the 1930s, U.S. senator and governor Huey Long ran a political machine throughout Louisiana with significant voter fraud.^[41]

In the 1946 Georgia gubernatorial election, a box of 58 votes for write-in candidate Herman Talmadge was unearthed in Telfair County, Talmadge's home county. The votes allowed Talmadge to place second, making him eligible to be chosen by the Georgia General Assembly as governor in a contingent election. An investigation by Atlanta Journal journalist George Goodwin uncovered fraudulent votes of people who were dead, had moved away or never existed. The discovery contributed to the Three governors controversy secession crisis in the state.^[51]
In the 1948 United States Senate election in Texas, according to Robert A. Caro, Johnson won his Democratic primary against Coke R. Stevenson due to electoral fraud, which included county officials casting ballots for absent voters and changing vote tally numbers.

Some historians believe the 1960 United States presidential election in Illinois, which John F. Kennedy won over Richard Nixon, was decided by fraud. Multiple judges and one independent prosecutor determined that the election was fair, although historian Robert Dallek, who wrote biographies on both candidates, concluded the Chicago machine run by mayor Richard J. Daley "probably stole Illinois from Nixon". According to Politico in 2016, "over a half century after the fact, it's impossible to judge what really happened." Nixon lost the Electoral College and conceded the election the following morning, although he encouraged recount efforts in Illinois and other states, which were shut down after setbacks in several key court hearings.^[57]^[58] In 1962, three Chicago precinct workers were convicted of vote tampering in the election.^[59]

In 1972, a Chicago Tribune investigation uncovered more than 1,000 instances of electoral fraud in Chicago on a March 21, 1972 primary day. The investigation resulted in at least 30 election workers being found guilty and sentenced. The newspaper won a Pulitzer Prize as a result.

In the 1996 United States House of Representatives elections in California, the Republican majority on the House Oversight Committee claimed to have found 748 illegal votes cast in the 46th district race between Republican Bob Dornan and Democrat Loretta Sanchez, including 624 by noncitizens. Sanchez won by 979 votes, so it would not have affected the outcome,^[80]^[81]^[82] and the House voted to dismiss Dornan's challenge in February 1998.^[83] The findings were highly contested^[84] and disputed by the Democratic minority on the committee, who pointed out that about half of those who registered as noncitizens were citizens by the time they cast their ballots.^[83] No indictments were brought by a grand jury after a yearslong criminal investigation into Hermandad, an immigrant rights group at the center of fraud allegations.^[83] The California Secretary of State did not press charges, concluding in April 1998 that the noncitizens identified had registered in error and not from criminal intent.^[83]

Mark Harris initially won the Republican primary by 905 votes, but multiple inconsistencies – only 19 percent of ballot requesters were registered Republicans, for example, but 61 percent of absentee voters selected Harris – and credible reports from workers hired by Dowless led to an investigation, refusal by the North Carolina State Board of Elections to certify Harris, a new election (in which Harris did not participate), and the arrest of Dowless and several other Republican party operatives for ballot harvesting and ballot tampering.^[104]^[105]^[106]
