Changes in subjective well-being predict changes in U.S. presidential, Senate, & House of Representatives election outcomes

Free and fair elections enable the nation’s citizens to elect candidates whom they believe best represent their interests. When deciding who to vote for, individuals may consider a host of factors that ultimately improve their subjective well-being. Using data from the Gallup Sharecare Well-being Index (N = 3,208,924), we examined whether changes in subjective well-being predicted U.S. presidential, Senate, and House of Representatives election outcomes from 2010 to 2020. We tested this effect at county (n = 1,652–3,061), metropolitan statistical area (n = 191–363), state (n = 50), and district (n = 389–427) levels. Pre-registered multilevel models supported the notion that regions with growing discontent tended to have larger increases in non-incumbent vote shares. Establishing a link between subjective well-being and electoral outcomes has the potential to realign policymakers’ priorities with what truly matters to their constituents, thereby facilitating the promotion of population well-being.
