<abstract>Large language models are increasingly used to simulate social and political audiences, but it remains unclear whether persona-conditioned generations provide coherent reception patterns or align with real public opinion. We study audience reactions to morally salient political messages, using Trump’s posts as a relevant case in point, through two theory-grounded human value frameworks, Inglehart-Welzel cultural map and Moral Foundations Theory. Across issue-specific message bundles, we analyze stance together with agreement, legitimacy, offensiveness, and endorsement, asking whether synthetic personas produce systematic reception differences, which persona dimensions explain those differences, and whether aggregate synthetic distributions align with matched Pew public-opinion patterns. The paper examines three related dimensions of synthetic-audience evaluation: internal differentiation, explanatory structure, and external plausibility. It contributes a reproducible study design for political audience simulation and an empirical account of where synthetic moral audiences are informative, and where they should not be treated as calibrated population proxies.</abstract>
