President Donald Trump's sustained efforts to reshape U.S. election rules and assert greater control over voting processes have consistently faced legal and political resistance, leading to limited success. These initiatives range from executive orders to legislative proposals, many of which have been thwarted by court rulings and congressional gridlock.

Recent Supreme Court and lower court decisions have barred several of Trump's sweeping executive orders aimed at changing national election rules. These rulings underscore the constitutional division of powers, which assigns primary authority over elections to the states and Congress, not the president.

One significant area of focus for Trump has been the integrity of mail-in ballots and the elimination of perceived vulnerabilities. His administration pushed for restrictive legislation, such as the SAVE Act, which proposed eliminating most absentee voting and requiring citizenship documentation for voter registration, alongside nationwide photo ID requirements. However, this bill has stalled in the Senate, with several Republican senators expressing opposition.

Trump's administration also pursued a multiagency effort to nationalize voter data and assist states in purging voter rolls. The Department of Justice sought detailed voter files from various states, including dates of birth and partial Social Security numbers. These requests were met with resistance from Democratic and some Republican secretaries of state, leading to federal lawsuits. To date, the administration has lost these cases.

Furthermore, a federal judge blocked the use of a revamped government tool, SAVE (Systematic Alien Verification for Entitlements), as a mass citizenship check. The program, intended to identify potentially ineligible voters, was criticized for aggregating sensitive personal data in a way that could lead to the wrongful removal of eligible voters from registration lists. A federal judge ruled that these changes infringed upon the privacy rights of American citizens and threatened the right to vote.

Trump's executive orders aimed at election reforms also faced judicial challenges. One order sought to require proof of citizenship for voters, but a federal judge placed a temporary block on it, later making the decision permanent. The judge cited the Constitution's lack of specific presidential powers over elections. Another executive order proposed a national voter list and empowered the U.S. Postal Service to determine absentee ballot eligibility, while also threatening local election officials with prosecution. This order was also blocked by a federal judge, who ruled that its provisions unconstitutionally violated the separation of powers.

Despite these setbacks, Trump's efforts have not been entirely without impact. Republican-controlled states have redrawn congressional district lines, a process that has seen support from Supreme Court decisions impacting the Voting Rights Act. Additionally, Trump has directed the Department of Justice to investigate voting and election operations, actions that have raised concerns among Democrats about potential implications for the upcoming midterm elections.

The president has frequently claimed, without evidence, that U.S. elections are subject to widespread fraud, particularly citing noncitizen voting. Research indicates that noncitizen voting is rare and accounts for a minuscule fraction of election fraud cases.

Legal and political analysts suggest that Trump's fixation on election rules stems from his unsubstantiated claims of fraud in the 2020 election. While many of his direct attempts to alter national election rules have been unsuccessful due to constitutional limitations and judicial opposition, his rhetoric and the actions of his administration have contributed to a polarized environment regarding election integrity. This has led to increased scrutiny and legal challenges from both parties around election processes. The Republican National Committee has stated its commitment to continuing efforts to ensure elections conclude on Election Day, indicating ongoing strategic activity despite specific ruling setbacks.
