Policy voting in U.S. House primaries

This paper uses exit surveys of voters in four House primaries to ask how well voters are able to use primaries for the purpose of giving policy direction to their congressional parties. The surveys found that nearly half of voters could not recall the names of any candidate and that 11% were uncertain or could not recall for whom they had just voted. The surveys also found that nearly 40% of voters could not offer a political evaluation - that is, a like or dislike having political content - about any candidate, and that fewer than a quarter could offer political evaluations of as many as two candidates. The surveys found no evidence of policy-motivated voting in three of the four primaries, but substantial evidence of it in one. Yet even in that one race, voters split their support among three candidates sharing majority voter opinion on the key election issue and thereby opened the way for nomination of a candidate not sharing majority opinion. The paper concludes from this evidence that voters in these House primaries, and probably more widely, made little use of them for the purpose of giving policy direction to their parties.
