Pennsylvania Poll Reveals Declining Trust in CDC, Tight Presidential Race
Locales: Pennsylvania, New York, Georgia, UNITED STATES

Philadelphia, PA - March 16, 2026 - A new poll released today by the Penn Biden Center for Delaware Policy paints a concerning picture of public health sentiment and a fiercely competitive political landscape in Pennsylvania. The survey reveals a significant decline in trust towards key public health institutions, particularly the Centers for Disease Control and Prevention (CDC), alongside a tight presidential race between incumbent President Biden and former President Trump. The findings highlight the growing influence of misinformation and political polarization on both health perceptions and electoral preferences.
The poll, conducted among 1,550 registered voters in Pennsylvania, demonstrates a dramatic drop in confidence in the CDC. Currently, just 38% of respondents express trust in the agency, a stark contrast to the 55% recorded in 2020, at the height of the COVID-19 pandemic. This 17-point decrease is not simply a reflection of the receding pandemic; it signals a fundamental shift in how the public perceives the reliability and impartiality of public health guidance.
Nicholas P. Jones, senior fellow and director of the Penn Biden Center's health policy program, attributes this decline to a confluence of factors. "We've seen a real erosion of trust in institutions that we all rely on to protect our health," Jones explained. "The pandemic exposed vulnerabilities in our public health system, and the subsequent spread of misinformation has further undermined confidence." The pandemic itself, while initially prompting widespread adherence to public health recommendations, ultimately became a breeding ground for conspiracy theories and distrust, fueled by social media and amplified by politically motivated actors.
Perhaps even more alarming is the respondents' perception of political interference. A majority - 63% - believe that politics plays too large a role in the decision-making processes of public health officials. This perceived politicization erodes the perception of objectivity, leading many to question the validity of health recommendations, especially when they conflict with pre-existing political beliefs. The aftermath of the pandemic saw numerous instances of state and federal health policies becoming entangled in partisan debates, further exacerbating this issue. We are seeing the long term repercussions of that politicization play out in voter sentiment.
Turning to the political arena, the poll shows President Biden maintaining a slight lead over Donald Trump, 48% to 44%. However, this margin falls within the poll's +/- 3 percentage point margin of error, indicating a virtual tie. Pennsylvania remains a crucial battleground state, and the close results underscore the difficulty either candidate will face in securing its electoral votes. With 8% of voters still undecided, the outcome remains highly uncertain.
The emergence of independent candidate Robert F. Kennedy Jr. adds another layer of complexity to the race. Currently polling at 7%, Kennedy appears to be siphoning support primarily from independent voters, potentially impacting the margins for both major party candidates. His focus on issues related to public health and skepticism towards established institutions resonate with a segment of the electorate disillusioned with the status quo. Analysts are closely watching to see if Kennedy's support will plateau or continue to grow as the election draws nearer.
The Penn Biden Center poll also delved into the role of social media in shaping political attitudes. A substantial 62% of respondents acknowledged the significant influence of social media on their views. However, this influence isn't viewed entirely positively. A large proportion expressed concerns about the proliferation of misinformation and the "echo chamber" effect, where individuals are primarily exposed to information confirming their existing biases.
"Social media has become a powerful force in shaping political discourse, and it's contributing to the polarization of our society," Jones stated. "It's important for people to be critical consumers of information and to seek out diverse perspectives." The rise of algorithmic curation, which prioritizes engagement over accuracy, has further exacerbated these issues, creating filter bubbles that reinforce existing beliefs and hinder constructive dialogue.
The poll's findings serve as a wake-up call for both public health officials and political leaders. Restoring trust in public health institutions will require transparency, objectivity, and a commitment to evidence-based decision-making. Addressing the spread of misinformation necessitates a multi-faceted approach, including media literacy education, fact-checking initiatives, and responsible platform governance. As the 2026 election cycle heats up, the ability to navigate these challenges will be crucial for both safeguarding public health and ensuring a healthy democracy.
