Early campaign economic perceptions can help to predict the national verdict on Election Day

It is well known that elections are determined by certain fundamental variables: internal factors that reflect voters’ long-term political predispositions and external factors that are unique to each campaign. Robert S. Erikson and Christopher Wlezien examine how one external factor, the state of the economy, compares to how voters’ internal factors evolve over the final 200 days of presidential campaigns. They find that while noneconomic factors dominate at the outset of the campaign, the economic component increases in salience as Election Day draws nearer and offers greater electoral predictability overall
