Obama Immigration Decision Leaves Marco Rubio Plan Floundering

President Barack Obama's surprise decision to halt U.S. deportations of young undocumented immigrants has all but killed a Republican effort to fashion legislation that could have won political points with Hispanic voters in November's elections.

Republican Senators, including Marco Rubio, had been working behind the scenes for months on a bill that would have allowed some children of undocumented immigrants a chance to stay in the United States legally while pursuing college or military careers.
