Do Not Call lists have been one of the more popular governmental regulations in some time. Pretty much across the board, people don't like being bothered by telemarketers, so their whining about have to deal with state as well as federal rules tend to fall on deaf ears. That hasn't stopped them, though, from continuing their efforts to get state do not call rules invalidated, arguing only the federal government has the authority to regulate them. But this really isn't about the power of state versus federal government. That's a smokescreen trying to cover up the real issue: that states have closed many of the loopholes in the federal rules that allow companies to contact people, including the nebulous "existing relationship" exception. This is a pointless battle by telemarketers -- regardless of what's legal or illegal, most people don't want to be called with sales pitches, and getting laws changed won't change peoples' attitudes. Instead of looking at DNC lists as something that's destroying their business, telemarketers should see them for what they are -- prescreening for people that aren't receptive to their messages.
