That's the issue here, the 30% argument is far too ham-handed to be taken as a plausible scenario. It's neither true now, nor is it certain for the future. The tiny states you listed are just as much an affront as Wyoming and Montana. But that's the purpose of hte Senate - to represent states as a whole and not be population dictated. That is their exact purpose in existence. There is no doubt that there is slight power advantage given to rural over urban. But there are valid reasons for that - if the large population centers are given full reign over everyone, it will create disparities so stark and unfair that it can jeopardize the health of the republic. Right now, where there are major urban centers, this already happens. In Illinois with Chicago and NY come quickly to mind. Voters on that outside of those cities have very different needs, needs that are often utterly ignored in favor of the urban needs. Now, do I want rural needs to trump them? Of course not, but the risk is high that if they aren't at least given some extra weight....they may be ignored (or exploited) entirely. And that's a not a healthy recipe. I can't envision a rational scenario in which large urban centers ever get ignored or exploited in the way that the reverse could happen. There is simply too much inherent political power contained in those places that rural america cannot match.
