“…We know a great deal about factors affecting voting in congressional races (e.g., Abramowitz, 1988;Tufte, 1974;Welch & Hibbing, 1997) and a good deal about the effects of money on outcomes in congressional contests (e.g., Gerber, 1998Gerber, , 2004Green & Krasno, 1988;Jacobson, 1978Jacobson, , 1990. Additional literature is expanding our understanding of actors who finance campaigns (e.g., Francia, Green, Herrnson, Powell, & Wilcox, 1983;La Raja, 2008;Magleby & Nelson, 1990), and about how different sources of money-outside expenditures, political action committee (PAC) funds, and self-financed campaignsmight correlate with candidate vote share (e.g., Alexander, 2005;Brown, 2013).…”
