I don't necessarily disagree. However, the tendency toward corruption comes with the territory in SoCal hispanic politics. Have you lived there? If you haven't, you might not comprehend the pervasive Mexicanization of local politics.
There are many legal immigrants from Mexico who support the Minutemen, but at the same time they will succumb to nationalism and vote for Mexican politicians they know are crooked.
I live in LA, so I am qute aware of what's going on.
But I repeat, the problem is NOT Villaraigosa's national origin, it's his membership in MEChA, leading role in the ACLU, and general support for gangs, that's the problem.
