decision on the issue of immigration:
to either become known as a moderate, inclusive party that rejects the nationalism of the Tea Party movement, reducing the enthusiasm of its base just in time for the 2012 elections,
or to become known as an anti-Latino party that embraces that nationalism, alienating the nation's largest and fastest-growing ethnic minority group and irreversibly damaging its demographic prospects.
Obama's motives in forcing the GOP to choose are more likely strategic than benevolent, and are unlikely to result in any useful short-term policy changes, but continuing to press these two legislative issues could highlight a clear, measurable policy difference between the two parties on a key civil liberties issue--just in time for the next election cycle.
The last sentence (of an excerpt of the SOTU) is a reference to the DREAM Act, which passed the House by a 216-198 margin during the lame-duck session but was filibustered in the Senate. It's possible, but unlikely, that it could still pass the House, and possible, but unlikely, that Senate conservatives could elect not to filibuster and let it through. But
both scenarios assume greater Republican cooperation on moderately progressive immigration reform, which would put more GOP legislators at odds with the very right-wing and nationalistic Tea Party movement. I don't think this is going to happen.
I also don't think that comprehensive immigration reform is going to happen within the next two years. Considering the viciously hateful, nightmarish mess House Republicans produced the last time they attempted to reform immigration law, under the leadership of a president of their party who was fairly moderate on the issue, I don't think the current, Tea Party-backed majority is likely to produce anything satisfactory.
