Republicans KNOW that if they were to kill that reform again, they would permanently lose the latino vote.
They know what the Latino vote is doing for Democrats, sanity, and other people. They know that the latino vote is ruining their opportunities to hurt people and society.
Far-right people like rupert murdoch, sean hannity, and glenn beck have changed their support to immigration reform. That is significant. As lindsey grahm said "We are not generating enough angry white guys".
The senate will pass reform. The house will pass reform with Democratic votes and a minority of republican votes. John Boehner even voiced confidence of passage. He knows he will be in big trouble if immigration reform fails.
Obama and Democrats have this.
