SACRIFICIAL LAMBS OR STRATEGIC POLITICIANS - POLITICAL AMATEURS IN UNITED-STATES HOUSE ELECTIONS

Why do hundreds of amateurs challenge entrenched U.S. House incumbents every two years? Previous work offers a range of explanations, from n aivete to love of politics. The most systematic study of this question concluded that amateurs challenge incumbents because it maximizes the ir chances of being elected to the House. This article argues that dis tinctions must be drawn between ''ambitious'' and ''experience-seeking '' amateurs because no single theory can explain amateurs' motivations . Ambitious amateurs respond to favorable district and national condit ions in their decision to run, like their experienced counterparts, wh ile experience-seeking amateurs do not.
