Well, this can be discussed, the short-term and the long-term answers are still unclear (https://www.google.se/amp/s/www.thelocal.se/20181122/timeline-this-has-happened-in-swedish-politics-since-the-elections/amp). Politics is getting more complicated than ever before. Not all political parties have clear and straightforward definitions of what is right, what is left or what is middle. The actual question still remains: is the Swedish politics on the way to take new trends towards the same political structure as in the USA, i.e. two strict block politics either democratic (socialistic) or republican (right).
Just after the September elections of 2018, it may have looked as if there are no middle parties, or middle solutions, but in reality the final outcome of the ongoing negotiations will soon be clear. This will clarify the position of the middle parties and their impacts on the Swedish politics. Indeed, the middle parties (C and L, although they still belong to the right block), in particular C, have actively mediated an agreement between the two blocks, o.e. V, MP, S on one-side and M, L, C, KD, SD on the other-side. But how then it comes that C and L though being in the right block claim mediation by being middle parties? The political parties on either of the extreme sides (V and SD), though the content of their politics is totally different, can’t be compared especially what concerns national conservatism. However, both V and SD have strict conditions to be enrolled in the Swedish politics (https://youtu.be/KWnXc29X_EI
; https://www.svd.se/just-nulofven-forst-ut-att-traffa-talmannen) but in practical terms they have little, or even no, possibilites to take active part in future decisions (https://www.aftonbladet.se/debatt/a/bKl4AB/sjostedt-ar-det-sana-som-mig-du-vill-gynna). Although what is going on is the result of democratic elections, the consequences can be counter-productive for Sweden as a whole. Some parties are, more or less, telling the same story “our way or the highway or no way at all”. The strategic question for Sweden now is what type of politics would we expect and for how long? It is unfortunate to have a polarized political situation where the political parties agree not to agree. This is of no ones interest.
Nevertheless, the situation has gradually changed and though the complex situation changes did take place, specially towards collaboration over the political blocks (https://www.svt.se/nyheter/annie-loof-vi-rekommenderar-lofven; https://youtu.be/iDmf6EvUR3Y). After all, there will be winners and losers, there are reflections from neighboring Scandinavian countries that C is a winner by actively “bridging” the gaps, to some extent, between the left and the right blocks. But, the Swedish support to the political leaders in particular C has declined considerably since the September 2018’s election (https://www.metro.se/artikel/nya-siffror-förtroendet-för-politiker-dalar-störst-ras-för-annie-lööf). The outcome of the election results of September 2018 clearly showed that block politics is dead. This has also been told and confirmed by many parties (S, L, C and M) except the far right SD and the far left V. So, now we are left by two alternatives, either to move away from block politics or to go back to block politics forced by far left and far right.
To repeat the elections again will not solve the existing block polarization and will not even give answers in favor of political stabilities as we may get answers clustering around the two extremes and thereby go back to the same dilemma of unstable block politics. Repeating the elections are associated with democratic risks, i.e. to get populistic, or undemocratic, alternatives either to to the left or to the right. In this case, we will put Sweden and the Swedish population in a long-term pendulum that will swing for ever from left to right and from right to left again.
