Why?
The main reason I oppose a national ID card is I am afraid at some point it may be used to track people for purposes it was not intended. I do not want to see the day in Americe where we are stopped at random and asked for identity. I have always felt the less the government knows about me, the better. I realize with all the databases that exist now, the government already knows more than enough- I just don't want to make it as easy for them as a national ID card would make it.
