Reno v. Condon

[Eric Segall]

I'm not sure if Reno v. Condon has been discussed before on this list but I
am having a hard time distinguishing it from New York and Printz and need
help.  It seems like the federal government was telling South Carolina what
it could and could not do with its DMV information and requiring South
Carolina to implement federal regulations vis a vis private purchasers of
that information. Why isn't that commandeering? The opinion is very short
and unhelpful. Any assistance would be appreciated.
