2014 after the party primaries for the mid-terms are done is more likely.
If we get presidential primary debates in 2014, then the deluge is truly here. No, I'm thinking of the window between the mid-term primaries and the mid-term general election. Once the Congressional primaries are over, there will be fewer Congresscritters who need to hold to extreme views. They'll either be already primaried, in safe seats, or in a competitive race where having a moderate position could help them in the general election.
If it doesn't get done in 2014, serious immigration reform will likely have to wait until 2018. The period between the mid-term primaries and the mid-term general election is the best time to approach some issues, especially if they involve a compromise between the parties. Immigration reform is just such an issue.
