When you steal an identity and drive, there is little to prevent the cycle from repeating. Hit and run, DUI, etc. are just additional charges to a life of crime that the Democrats not only accept but openly encourage.
Don't forget the leadership of the Republican party. From Bush on down, there's no additional crime an illegal alien can commit that will dissuade the country-clubs from their amnesty plan. McCain is full-steam-ahead with "reform."
