The lastest politics of defamation by out-of-context quotation will not work on Sotomayor. She made a statement indicating that her experience was informed by her background. So did Alito.
Sotomayor's best recommendation seems to be a wealth of experience and an inclination to get deep into legal argumenation without fear.
We still don't have a picture of her core beliefs as to legal interpretation. She may be pretty conservative.
So far I think Rush Limbaugh has been a swell leader of the Republican meanistream (if you're a DEMOCRAT)
