As a footnote to the attempted assassination of Gabrielle Giffords, it's worth noting that House Speaker John Boehner has denied a spot on the immigration subcommittee to Rep. Steve King (R-Iowa), the hard-right anti-immigrant firebrand. King is none too happy about it, telling National Journal, "John Boehner isn't very aggressive on immigration." King was sure to cause headaches for his leadership, so this was probably a deft move on many levels. But it would be nice to think it's also an example of a new restraint taking hold in Washington. We'll see.
