To his great credit, Jim Webb, to whom I donated when he knocked off the Great Theocratic Hope George MacacAllen, is risking significant political capital on doing something about it. See here, here and here.
Addendum. Webb was mentioned as a vice-presidential nominee and has campaigned with Obama. Is he doing this with Obama's support or at his instigation? (Because Obama does not want to get accused of playing racial politics.) The possibility warrants mention.
Whatever. I strongly support what Webb is doing.
