In a dramatic shift that could have significant political ramifications, support for President Donald Trump among a crucial demographic has experienced what analysts are calling a "stunning" collapse. New polling data reveals a massive erosion of approval from voters under the age of 30.
A "YUGE" and Unprecedented Decline
CNN's chief data analyst, Harry Enten, highlighted the alarming trend during a segment on "OutFront" with anchor Erin Burnett on Thursday, December 5, 2025. Enten, known for his deep dives into polling spreadsheets, expressed astonishment at the speed and scale of the drop.
The president's net approval with young voters has plummeted from a positive +10 points in February to a deeply negative -46 points today. This represents a staggering swing of 56 points in less than a year.
"Look, I think the word of the day, to borrow a phrase from the current president: YUGE, YUGE," Enten stated, emphasizing the magnitude of the change. "Look at this drop! I’m laughing because it’s down to minus 46 points. That is a drop of 56 points among voters under the age of 30."
Key Demographic in Freefall
Enten was quick to point out the strategic importance of this voter group. Young voters were a key component of Donald Trump's successful 2024 re-election coalition. Their rapid departure from his base of support marks a severe and potentially damaging reversal.
"This type of drop happening so quickly is just..." Enten said, searching for words. "You know I spend my days on the spreadsheets. You just don't see drops like that. It's stunning."
The data suggests a wave of overwhelming dissatisfaction is rolling through the under-30 electorate. While the specific reasons behind the plunge were not detailed in the segment, such a sharp decline typically points to a reaction to recent policy decisions, economic conditions, or major political events.
Implications for the Political Landscape
This rapid erosion of support among younger Americans presents a clear challenge for the Trump administration. Rebuilding favor with a demographic that has turned so sharply negative is a difficult task, and the trend could influence policy priorities and political strategy moving forward.
For political observers and opponents, the numbers provide a striking data point about the current national mood. A 56-point swing in any demographic is exceptionally rare in modern polling, indicating a significant and concentrated shift in public opinion.
As the political cycle continues to evolve, all sides will be watching closely to see if this decline stabilizes, deepens, or potentially reverses. The loyalty of young voters, once considered a strength for the president, has now become a pronounced vulnerability.
