Why would an Arizona Senator vote for SB 1070?

THIS HAS NOTHING TO DO WITH INTELLEGENCE. SOME LATINOS SELL DRUGS TOO, ITS A RECESSION, EVERY ETHNICITY OR MINORITY SELLS DRUGS; BLACKS,CHINESES,ANGLOS, AND EVERY OTHER GROUP IN AMERICA. WHY DO THEY SELL THE DRUGS. BECAUSE THE OUTSTANDING DEMAND FOR IT. JUST BECAUSE YOUR IGNORANT ABOUT YOUR COUNTRIES "DRUG PROBLEM", DOESNT MEAN YOU CAN POINT FINGERS AT A CERTAIN GROUP OF PEOPLE.
