The aim of the paper is to analyze the factors determining the likelihood of reelection of Polish mayors. In order to identify the factors impacting the likelihood of reelection, the author estimates the parameters of the binomial model. The results show that spending in the election year, especially on housing, is greatly appreciated by the inhabitants of cities. The mayors who are very likely to be reelected are leaders of cities that are successful in acquiring EU funds, where the labour market is stable, and the material situation of inhabitants and businesses does not deteriorate during their term. Cities that are capitals of voivodeships offer a greater likelihood of reelection, as do those formerly in the Austrian partition or on the so-called Reclaimed Lands of Western Poland. Variables belonging to the domain of sociology of politics have an equally significant impact on the analyzed likelihood.
