The purpose of this study is to investigate whether there has been a divergence between the aims of LO and the Social Democratic Party in Sweden during the period 1994–2018. This study also has the purpose of investigating whether this has affected which party the members of LO will vote for in the Swedish elections. The hypothesis of this study is that there has been a divergence between LO and the Social Democratic Party and that the aims differ more in 2018 than they did back in 1994. This is a qualitative text analysis with the purpose of both being descriptive and explanatory. This study is scientifically relevant as it highlights the role of ideology in Swedish politics and how this can affect voter support. It is also interesting for people who are not researchers since this affects Swedish politics and therefore everyone who lives in Sweden. This study shows that there has been a noticeable divergence between the aims of LO and the Social Democratic party in Sweden during the period of 1994–2018. Back in the 1970:s there was also a divergence between the aims of LO and the Social Democratic Party. During the 1970:s, the members of LO to a lesser extent voted for the Social Democratic Party which supports the hypothesis of this study. The hypothesis was correct but the noticeable divergence was not the divergence that was expected since the study showed that LO more and more had switched focus from broad policy areas to labour policy. The answer to the question whether this divergence probably has affected which party the members of LO will vote for or not, is yes. It is very probable that the divergence between LO and the Social Democratic Party has affected which party the members of LO will vote for.
