The changing political landscape means that Republicans are more open to the idea of legalizing the illegal immigrants already in the country and there appears to be more acceptance of giving legal status to those undocumented immigrants who were brought by their family members as children. While advocates are asking for a path to citizenship for all undocumented immigrants, what is more likely is a form of permanent residency for adult illegal immigrants while a path to naturalization for DREAMers.
The problem is that if this amnesty is given by a Democratic administration and with already high level of support among immigrants in general, and among Hispanics in particular, by allowing millions of these individuals become citizens, Republicans would have ensured permanently minority status in Congress and a zero probability of winning the White House. A solidly reliable Cuban community for Republicans has also increasingly been voting for Democrats and that makes it less likely that they will vote for their own demise.
That is why I am hearing that GOP members of Congress are more likely to support a stripped down version of DREAM Act that will give legal status to DREAMers if they complete college or serve in the Military and that would give them a work permit for four years and a right to apply for a green card. It seems that they will not be able to apply for naturalization ever.
