Marco Rubio tries to find a middle ground between water and fire. It looks like that he is more a politician for the sake of staying in politics, than a statesman not afraid of boldly using water or fire when needed to do something important. Mr. Rubio hopes to enhance his political career by riding the immigration issue. The last several years have proved that there is no compromise between fierce nativists and proponents of more open immigration policies. Compromise is not the way to resolve our immigration mess.
