No Experience Required: Early Donations and Amateur Candidate Success in Primary Elections

The electoral dominance of “quality” candidates—political insiders with a history of holding office—is well-established. However, research on the recent rise in successful political neophytes is less studied. Despite longstanding trends in the predominance of experienced candidates in primary elections, nearly half of all quality candidates who ran in non-incumbent races lost to a candidate without prior electoral experience in 2018. In this article, we investigate the success of political newcomers in elections for the U.S. House of Representatives by examining a topic often overlooked in the growing literature on primaries: campaign finance. We show that, from 2016 to 2020, political newcomers saw (1) greater success in future fundraising, and (2) an increased likelihood of primary election victory when they garnered more early contributions from outside their district. This contrasts with prior elections, where early money from inside a candidate's own congressional district served as the strongest predictor of future fundraising and electoral success.
