Election promises and their fulfillment are subjects that have been studied quiete extensively within the academics, this thesis seeks to investigate how the promises given by the red-green block in Sweden during the mandate periods of 2014-2018 and 2018-2022 have or have not been fulfilled. The theoretical basis used in this thesis is that of Rational choice with Gunnar Sjöbloms three arenas that parties engage in and that of the responsible party model. In this study the method used is a theory consuming one, this type of method uses multiple theories on the same case and investigates how well each of them can explain the phenomena. The promises were taken from each of the parties manifestos from each mandate period and following this some were left out since they could not be fulfilled with national level policies. The results of the study showed that mandate period 1 followed previous results and studies quite well whilst mandate period 2 results differed from previous results. A number of factors could help explain this vast difference and with these variables accounted for the results became more in line with previous studies results. The study showed that for the most part parties do keep most of their promises to some degree but how these studies also must be conducted on a case by case basis to achieve the best results.

There is a large part of the population today whose perception of Swedish political parties assumes a pronounced distrust. Often, this mistrust is linked to whether politicians act on the election promises made during the election campaigns. This is a view that opposition parties often encourage through negative criticism during election campaigns and media platforms. The paradox that arises then becomes markedly confusing because research actually shows that parties almost fulfill most of the election promises made.   Furthermore, a society characterized by widespread distrust of political activity risks gradually undermining the representative democracy system, which may lead to diminished democratic legitimacy. In the field of research, therefore, there is often talk of making knowledge regarding election promises more accessible to voters, who then may examine political activity more effectively themselves. The study has analyzed the Alliance's and the Social Democrats' election promise fulfillment during the mandate periods 2006-2010 and 2014-2018, through qualitative analysis of the election manifesto and data collection from the Riksdag's website. The aim was to investigate and compare which of these party organizations best achieved good representation during the alternative government periods through clear method choices that could present data in an easily accessible way.   The study arrives at a result that shows a balancing election promise fulfillment between the Alliance and the Social Democrats, with a small statistical advantage for the Alliance. It also shows how the Alliance has achieved a slightly better representation by succeeding in fulfilling more election promises in key policy areas that the party organization has given higher priority to during the election campaigns and election manifestos.
