Wither Immigration?

Remember a few months ago when the conventional wisdom had it that Democrats needed to be in a state of panic about how anti-immigration sentiments were going to run them out of down. At the time, I tried to cite polls which kept showing that the audience for anti-immigrant politics was, though loud, actually pretty small. A lot of people came back at me with the notion that, well, the incredible power of the immigration issue isn't something you can see in the polls.

And maybe not, but here we have Captain Amnesty himself looking set to secure the Republican Party's nomination -- a turn of events which certainly makes it seem like the polls were right and this simply isn't an issue that very many people care all that deeply about.
