While Supreme Court nominations have become increasingly high-salience political events, we know little about their prioritization relative to other issues by core con- stituency groups. We examine how individual donors and the mass public prioritize nominations, as well as factors they believe presidents should consider when selecting judges. To do so, we constructed original questions for a survey of over 7,000 validated donors and a comparison general population sample. We find donors are substantially more likely to prioritize nominations than their general public co-partisans, particularly Republican donors. Further analysis suggests the prioritization gap is consistent with theories that donors are motivated to move policy towards the ideological extremes. Analyzing policy positions, the largest donor-public difference occurs for diversity in appointments, but for all positions we find smaller differences than for prioritization. Overall, the findings highlight donors’ policy priorities may diverge from those of the public even more than policy positions do.
