You guys are funny--a bit dense, but funny.
Sotomayor was paid to write a book--a basic commercial transaction that is completely above board and one that many public figures engage
in. I presume she reported the deal and it wasn't secret. Random House is a book publisher and not engaged in partisan political activities. Sotomayor
did not go on luxury trips with Random House executives, and we can be quite sure that Random House has not bought any houses from Sotomayor while Sotomayer relatives continue to live in said house.
Harlan Crow is a major conservative political donor and activist with an interest in many different political/commercial issues. He's made Thomas his bought and paid for judicial lackey. He's had Thomas on a string for many years. Various other officials with conservative special-interest groups have been on luxury trips with Crow and Thomas. Thomas has never reported any of the many financial favors that Crow has done for him--which suggests strongly that Thomas knew his activities were unethical if not unlawful and tried to keep them a secret.
In other words, there is nothing remotely similar here--it's the usual lame stab at equivalency by conservatives. A one-time book deal has nothing in common with secretly taking money and many other favors from a political donor for many years. And you can bet that Crow--and other GOP/right-wing political donors--have done other favors for Thomas that have not yet come to light. I have zero doubt about that. There's probably a lot more to the Thomas scandal that's not yet public knowledge.
As for whether Sotomayor should have recused herself from the Random House case, we don't know what the case was--but it was likely commercial and not political, which is important. Not exactly the same as not recusing yourself from a case in which your radical wife was deeply involved. I'm not saying Sotomayor shouldn't have recused herself--maybe she should have--but I've not yet seen what the case was about. But her one-time book deal should not be lumped together with what the corrupt Thomas has been doing.
