“…Under this scenario, a candidate may benefit from adopting a more extreme policy position because of the net gain in campaign contributions, which could be used to mobilize likely supporters, attract uniformed and undecided voters, or both (Aldrich, 1983(Aldrich, , 1995Moon 2004). This distinction about the behavior of campaign contributors is analogous to the distinction made in the literature on voter participation between "abstention from alienation" and "abstention from indifference" Ordeshook 1969, 1970;Hinich et al 1972;Adams 2001;Adams and Merrill 2003;Plane and Gershtenson 2004). For example, Adams and Merrill (2003) show that if voters abstain from alienation (when participation depends only on the proximity of the nearest candidate), candidates will diverge in the policy space.…”
