Via Allahpundit who observes the politics behind this (and every other speech Marco Rubio delivers):

This speech isn’t aimed at you and me. We’re ideologues, and he kissed off the ideologues when he decided to support an amnesty bill. It’s aimed at the majority who pay attention to the news one or two hours a week, like the idea of bipartisan compromise and comprehensive immigration reform even though they really don’t know what’s in the bill, and will enjoy listening to a fluid hopeful communicator like Rubio talk about the promise and glory of America as a contrast to stiffs like McCain and Romney. The guy knows who his audience is, and he knows what he’s doing. That’s the one consolation for border hawks if he ends up as nominee — he’ll certainly, certainly be better at getting his message out than the last few nominees were. Who knows? Instead of losing 73 percent of the Latino vote next time, we might only lose 65.
