There has been a lot of writing on the flirtation by Maria Wetterstrand to social liberals on Newsmill. This discussion on Newsmill was better than the politics file of (MP) on their web site to explain their relative position. I then browsed the politics file on their web site and found no occurrences of the word "jämlikhet" as used by the social democrats. That would be "equality". If this is true, I can understand the flirtation because I found out that "jämlikhet" is a key word in the distinction between Alliansen and the Red-Greens. Jan Björklund, for example recently pointed out on the "Landsmöte" of (FP) that it is necessary to accept different effective salary levels.
Johan Norberg speculated about the possibility for Alliansen to balance out (SD) with (MP) in the next election which might not really be possible.
What is perhaps most interesting with this find, if relevant, is that it might not be possible for (MP) to function in the Red-Green alliance because of this ideological deficit. A socialist marker. Magnus Andersson, however, brings up factors that are against societal development that then solidly places (MP) aside of Alliansen and (S) + (V) as pointed out by Birger Schlaug. However, Fredrick Federley thinks (MP) is socialistic in other ways.
