According to Tom Tancredo, La Raza is "a Latino KKK without the hoods or the nooses." On one reading, where hoods and nooses are taken as metonyms for intimidation, murder, and the intentions that produce them, I suppose that's correct, but it renders his point empty. The reason that we dislike the KKK is that it intimidated and murdered lots of people. Take out the violence, and you just have a peaceful ethnic organization that fits nicely within civil society.
The Sotomayor nomination is really looking like a political masterstroke from Obama. Even though Senate Republicans are wisely holding their fire, the racist wing of the party is going bonkers. In addition to the racists, people who want to run for president in 2012 or gain short-term favor from the base will an incentive to go up against Sotomayor, and that will supply plenty of crazy villains to drive Hispanics closer to the Democrats.
