CPAC 2021 has seen a dramatic decline in attendance and sponsorships, with former President Donald Trump's influence on the event waning. Nikki Haley's speech was met with a polite but only mildly interested audience, and chants of "Trump 2024!" echoed through the hall as she left. Al Cardenas, a former chair of the American Conservative Union, noted that the event had been boosted by its ties to Donald Trump, but now appears to be losing relevance.
