“…In reality, party platforms and candidate positions rarely converge to the position of the median voter (Ansolabehere et al, 2001;Burden, 2004;Frendreis et al, 2003;Jessee 2010). Parties adopt more extreme positions to woo party activists (Aldrich, 1983;Aldrich and McGinnis, 1989;Frendreis et al, 2003) and primary voters (Burden, 2004;Owen and Grofman, 2006), or to deter abstention (Downs, 1957) or the entry of an independent or third-party candidate (Lee, 2012). Candidates may also have policy preferences of their own that are more extreme than those of the electorate (Aldrich, 2011;Calvert, 1985;Wittman, 1983).…”
