Yesterday, the US Senate voted 82 to 15 to let immigration reform come to the floor for the first time in decades. The vote was overwhelming, but nobody thinks it guarantees passage, and some opponents are pushing what supporters call "poison pills." Today, Senators on both sides of the aisle were lined up with amendments. There are bitter differences over border security, the need for workers and whether jobs should be saved for those born in this country. Democrats want to cement their hold on Hispanic voters. Some Republicans want to woo them away. But, is the "path to citizenship" really "amnesty?" We hear about the opening act of a drama that's taken decades to reach the political stage and we'll look at possible outcomes.
