I Wish I had Thought of this First

From Glenn Greenwald's latest post.

But beyond that narrow point, why isn't this race-based analysis being applied to others who are endorsing outside of their party? I don't recall Joe Lieberman endorsing any hard-core conservative national politicians before this year, when he has spent much of his time cheering for and appearing with the McCain/Palin ticket. Using the Limbaugh/Buchanan/Halperin logic, isn't it fair to assume that at least a significant part of Lieberman's motive in endorsing McCain -- if not his entire motive -- is that he and McCain are both white, whereas Obama isn't? What's the difference between making that race-based assumption about Lieberman's endorsement and making it about Powell?

Yeah, pretty much.

I could have fun with that idea though.
