Please provide more clarifications on some of your responses.

Example: Qualitative (Ordinal) - Ruling, Opposition and Independent - appear to be Nominal and not Ordinal. Just like different parties, these can be taken as different roles played by elected members. A better example can be a survey on how happy the citizens are with the performance of the government - A rating from 1 to 5 where 1 is Unsatisfactory to 5 being Excellent.

Example: Quantitative(Discrete) - Portfolio (Home, Finance, Railway, etc) - Again the way it has been described appears to be more like a Nominal data rather than Discrete. If you word it as Number of members working in each Portfolio (Home, Finance etc) - then it becomes a better example of Quantitative(Discrete).
