Question:  Why do we want to increase the total number of voters?  Even asking this question in America in public is seen as blasphemy, but if you go into the political science or economics department of any university, it's a valid question.

Voter ignorance is not only the strongest finding in political science, it may even be the strongest finding in all of social science.  It is so well supported by the evidence that it has never seriously been contested since it was first studied back in the 50's.  To my knowledge, there are no political scientists who believe that voters are not ignorant. Not even one.  

Now, there are competing theories for WHY voters are so ignorant, but nobody disputes the fact that they are, in fact, ignorant of politics.

It seems like we'd be better off trying to educate and inform those who are already voting before we increase the total number of ignorant voters.  I don't see what increasing the total number of ignorant voters would accomplish.
