Does the local organisational presence of anti-immigrant parties affect their chances for electoral success? In order to answer this question, the article explores the potential of a supply-oriented explanation to anti-immigrant party success by examining the electoral advancements the Sweden Democrats (SD) made in the 2006 and 2010 elections. Our results indicate that traditional demand-side explanations to anti-immigrant party success can be successfully complemented by an ‘internal supply-side argument’ to make the electoral fates of these parties more intelligible. Whether the SD had a local organisational presence had a substantial effect on its results in the national election and on the probability of gaining representation in local councils. Thus, the party’s fate in the national as well as local elections was largely determined by whether or not it had a local organisational presence in Swedish municipalities.
