Concerning the ideological disproportionality of the results, of course the FDP and the NDP would never work together, that I realize. I was including them together as part of the non-leftist electoral majority that won something like 52.5 to 53% of the vote. Is is plausible to include the Ecological Democratic Party on the right? Seems like the are to the right on some issues.
By my count I get about 45.3 % of the vote to leftist parties (SPD, Linke, Greens, Pirates, Animal Welfare, Marxist Leninists, Violets), and the aforementioned roughly 52.5 to 53% to non-leftist groups, assuming we can count Ecological Democrats, Bavarian Party, Alliance for Germany together with the bigger parties. The 5% threshold law has worked its random and arbitrary electoral magic yet again.
If voters could have a second choice to be used if their party didn't cross the threshold, how would Afd, Pirate and FDP voters have responded?
I made the argument before that Animal Welfare might be considered Right just like Ecological Democratic Party should be considered Right. Both are back to nature parties which I can argue has roots in the NASDAP regime.
