Sequester is not something new, contrary to what pundits may claim. In fact looking at a 2010 Congressional Research Report, one finds that in the past 40 years sequesters and government shut-downs have happened more then one would believe. Between fiscal year 1977 to 1980 there was 6 funding gaps resulting in government shutdowns ranging from 8 days to 17 days. The fiscal years of 1981 through 1995 saw 9 funding gaps and government shutdowns. In 1996 under President Clinton there was 2 funding shortages resulting in shut-downs which were 5 days and 21 days in duration.
So why do these shortages and subsequent shutdowns occur?
