People don't want to know the issues that don't effect their everyday lives. In this country at least, it seems to me that everyone *feels* so damned busy with doing as they must to pay the bills, provide for their families, or otherwise just make it to the next day. Human Nature has it that humans will look after their own interests first and foremost, and will often further it beyond "necessity" to ensure that their interests remain defended. Combine these two tidbits with the fact that there is a subset of people who make it a career to be informed in the methods of promoting their own interests in our society, and now you have the real problem.
Need to convince everyone that reasonable term limits and an informed voting populace are necessary for the success of democracy? Then figure out how you get past the barrier of apathy caused by people's *busy* schedules.
