As the American economy sags, the race for the presidency gets tighter--except in one dimension. Hispanic Americans continue to support Barack Obama by an astonishing 61%-to-27% margin. Were Obama to win, it might well be because of his attitudes on one issue: immigration. But it is an issue on which he will be unable to enact any of his preferences, let alone those policies that many Latinos support. The Republican Party has taken a tough stand on the topic. Democrats have their own bright lines. That means America's immigration system is likely to stay as it is right now--utterly broken.
