Also,keep an eye on party dissent(that’s where Wels’ or Breitscheid’s discipline ability come useful),for almost every politically positive effect in the game are multiplied by (1-dissent),alas,few of the negative ones are,which is probably the reason your middle class/unemployed campaigning drives sometimes backfire horribly(high dissent+high antipathy for socialism &no volkspartei/too high unemployment respectively )
