I think it's more difficult now, because the financial accounting standards are more complete. There are very few areas left where government has a lot of discretion to report certain things. I would think the Comptroller General and the people working there should be adopting the same principles year after year, so I would think not.
Policy decisions could affect a financial situation if there are a lot of transfers or a lot of money is given, but those would be obvious in the financial statements.
