This chapter explores the electoral geography of Chega's support and the factors contributing to its success. Utilizing aggregate electoral data from Portuguese municipalities and parishes, I place the geographical distribution of electoral support for the radical right in Portugal within existing traditional patterns: Northern Portugal, with a history of small landowners, has leaned to the right, while the South, characterized by large landholdings, has traditionally leaned leaned left. Within this context, Chega gather higher levels of support in the South, particularly in Algarve and Alentejo. To shed some light on these patterns, I analyse economic and cultural factors. While economic grievances like unemployment and inequality may partially explain Chega's appeal in poor regions, cultural grievances have also been believed to play a role. The chapter shows that contrary to expectations, Chega support is not higher in areas with lower levels of education. However, analysing data from a range of recent elections I find a positive correlation between the Chega vote share, the size of the local Roma community and the percentage of foreign nationals.
