What is the Governments Fiscal Stance? and how does this impact commercial real estate?.

Some questions to consider are as follows: Whats the percentage of federal, state and local government spending for goods and services as a part of GDP? Has this changed over time? Any forecasts to predict a percentage change in the future? Does the government spending number found in the GDP report capture all government spending? What about transfer payments such as Medicare? Deficit issues would come into play here, as well.
