I think a lot about the example of the 1949 CDU in West Germany, because it shows you can re-establish a party of the centre right that, while it will probably have an objectionable number of fascists from the former regime, will at least be a responsible player in a democracy
Every functioning democracy needs a party of the left and of the right - and both within the framework of accepted rules of a liberal constitutional order. One day I hope we get that back.
