More like prison and then banishment. I don't get why so many people think that illegal immigrants would take a very high risk, very low reward deal as voting without citizenship. Most citizens don't even like voting, so would it even be a high risk, moderate punishment deal? By analogy, it's as asking someone to be a drug mule, and if they're successful they get to wait in an extra line at the DMV. Would you take that deal?
