Tip of a very large iceberg.
I think you can add to this mess the fact that ALL college students attending school out of their home town are ripe for double voting. Once at school- absentee at their home address.
Considering the high number of college students in the USA, I think this is just as serious a problem, and it has to stop. I only get one vote, and I am legal. This should be corrected before 2006 elections.
