No they upper and lower house is seperate. So a conservative POP (i.e. one who is happy with how things are) may also like the Liberla government. So they vote for a Liberal lowerhouse and a Conservative Upper House.
It is a bit... bizzare... So, for instance communistt POP which is happy with social reforms introduced by communist governement will be voting for communist party (lower house) but in upper house he willl be represented as conservative???
Am I understand it right?
