nah, their politics will do best for sweden and it's a fact. Swedish democrats could argue that 5000-10000 immigrants / year will be too much and therefor not be as good as with their politics. that's only their opinion tho.
there will be selfish votes, ppl living on social welfare will obv vote S/MP/V/SD. but from an objective perspective those ppl are parasites of swedish welfare in which M wanna take care of.
so ye, M is the best party by fact. other parties however will suit you/minorities better. but as a whole M is best, no matter what opinion
