As the 2024 U.S. presidential election cycle intensifies, former President Donald Trump faces mounting challenges, most notably a significant slide in public approval. Recent polling data from several national and independent sources reveal that Trump is experiencing severe declines in support, especially among independent voters—a group widely recognized as pivotal in determining the eventual outcome of the upcoming election.

Trump’s Sinking Approval with Independents
According to a July 2025 Quinnipiac University national poll, just 21% of independent voters hold a favorable view of Trump, marking a new low for the former president since he entered national politics in 2015. The same survey shows his unfavorable rating among independents ballooning to 74%. These figures are corroborated by other recent polls, such as a Wall Street Journal poll published in July 2025, which indicates that Trump’s overall approval rating has fallen by nearly 5 percentage points among independents since April, now standing at 24%.

These low marks come at a crucial time, as the independent voting bloc has historically acted as kingmaker in swing states like Pennsylvania, Arizona, Georgia, and Michigan. In 2016, strong independent support was a cornerstone of Trump’s upset victory. In 2020, a shift away from Trump among these voters contributed heavily to President Joe Biden’s win.

Key Factors Driving the Decline

Several dynamics are contributing to Trump’s deepening struggle with independent voters:

• Legal Troubles: Ongoing criminal and civil trials, including charges related to election interference and classified documents, have dominated headlines. While Trump’s legal team claims these are politically motivated, independent voters appear less convinced, with 62% in a recent Ipsos/Reuters poll saying the indictments harm their view of Trump’s character and fitness for office.
• Polarizing Rhetoric: Trump’s continued rhetoric about the 2020 election being ‘stolen’ and repeated attacks on institutions have alienated moderate and swing voters. A Pew Research Center survey found that 67% of independents consider Trump “too divisive” for national office.
• Voter Fatigue: After nearly a decade in the national spotlight, polling by Morning Consult shows almost 60% of independents want “new leadership and fresh ideas” instead of a Trump return.
• Policy Positioning: Independents have expressed concerns about Trump’s positions on abortion rights, healthcare, and trade, with many citing these issues as reasons for their declining support. For example, a recent NPR/Marist poll found that Trump’s proposed restrictions on abortion have pushed over 18% of formerly supportive independents into the ‘undecided’ or ‘opposed’ category.

Comparisons with Historical Trends

Trump’s approval among independents is not only lower than during his presidency but has dipped below the lows seen by recent two-term presidents like George W. Bush and Barack Obama in their post-incumbent years. While both Bush and Obama saw rebounds among independents after leaving the White House, Trump’s post-presidency approval has remained stubbornly negative.

According to cumulative Gallup data from 2017 to 2025, Trump’s average approval rating among all voters post-presidency is 38%, but just 24% among independents—well below the 30+% averages retained by his recent predecessors. This suggests deeper and perhaps more lasting hurdles to reassimilate this crucial voting bloc.

Implications for the 2024 Campaign

The slide in independent support is a red flag for the Trump campaign and the Republican Party. With close races expected in key battleground states, winning a significant portion of independents will be essential for any path to victory. This is particularly true as third-party candidates—such as Robert F. Kennedy Jr. and Cornel West—are polling competitively, further complicating the electoral map and risking vote-splitting among anti-establishment voters.

Republican strategists are now grappling with the challenge of broadening Trump’s appeal beyond his enthusiastic base, which remains solid at around 80% among GOP voters. Recent efforts have included adjustments in campaign messaging on abortion, outreach to minority communities, and attempts to highlight economic achievements during Trump’s tenure. However, the polling indicates these moves have yet to meaningfully shift the opinion of independent voters.

Democrats, meanwhile, see an opportunity to capitalize. The Biden campaign and allied groups have launched targeted advertisements in swing states focusing on Trump’s divisiveness and legal woes. According to AdImpact, Democratic spending on negative Trump ads has more than doubled from the same point in the 2020 cycle.

Expert Perspectives

“If Trump can’t raise his numbers with independents by even a modest margin, his campaign is in serious jeopardy—especially in states decided by razor-thin margins,” said Dr. Emily Caldwell, a political scientist at the Brookings Institution. “While his core supporters are unmoved by scandals or controversies, elections are ultimately decided by voters who are less emotionally committed.”

Republican pollster Frank Luntz added, “The risk is that persistent negative coverage will not just keep independents at bay but depress their turnout altogether. That’s a threat not just to Trump but to the entire GOP ticket.”

The Road Ahead

With the campaign trail heating up and critical debates looming, Trump and his advisors are reportedly reconsidering some of their messaging and seeking new surrogates to bridge the gap with undecided voters. The coming months will be essential in determining whether the former president can recover lost ground or if the slide in independent support proves permanent.

As Trump prepares for upcoming rallies and debates, all eyes will be on whether his campaign can adapt quickly enough to stem the tide of growing disapproval—particularly from the voters who historically have swung national elections.
