Actually Koskie was a Minister under the Conservatives, and then later left for the NDP. The Koskie family have been long-time NDP supporters going back to at least the Allan Blakeney years.  

I think this whole controversy really calls for a page entitled Saskatchewan Legislative Assembly Expense Account Fraud Scandal, where the charges and convictions of each member, and support staff like Scraba can be described in detail.  There is a book entitled "SaskScandal" at your local library which might be useful as a starting point, and further, I am sure NDP contributors have additional information they might want to share.  Any time you have a breach of trust in government, or fraud against the Crown, it is important that such not be minimalized or trivialized, irregardless of political party involved.
