"... but that anecdotal evidence showed it was hurting legalized casino-style businesses in Minnesota."
Ahh, so it's about protecting the in-state businesses by artificially eliminating competition. Yeah, that sounds legal. Perhaps they would like the ISPs to block access to amazon.com as well, since that most likely hurts the in-state retail establishments. It would also be a good idea to have the ISPs block access to netflix.com since that likely hurts the in-state video rental establishments. Oh hell, let's just have the ISPs block access to everything except for the websites of in-state businesses, and state and federal government sites. People may get a bit upset, but we have to do something to protect the state's interests!
