Something like the Prime Law of Politics applies everywhere and at all times; things tend to stay the same even with apparently "large" political changes, because in mostly democratic countries, the people have what they want, even if they complain about it.
We'll also see laws flapping back and fourth between administrations. This already happens with some funding for NGOs and they hate it (funding for birth control and abortions in sub-saharan africa is one notable example). It's going to be very stressful.
Should we be able to chart a consistent course on issues where there is no broad agreement among the people? Should the government involve itself in such issues at all, rather than leaving highly controversial purposes to be accomplished by voluntary means?
