If you don't want to compromise your principles—not even as a tactic of political war—then democracy with winner-take-all elections will not work for you. At all.
Indiana used to have multimember districts ~ about 25 different people represented Indianapolis/Marion County ~ and an organized and dedicated group could push through a candidate who had 2.5% popularity.
The courts changed that (the one man one vote thing) and then the legislature changed it permanently.
It was fun ~ HUGE ballots!
This sort of thing was actually quite popular with the Germans and Danes who settled there in the 1850s ~ shame to see that tradition disappear.
