All 50 states have the same language, the same general culture, have fought the same wars, vote for the same 2 political parties, watch the same media, and more or less have the same economy.

But really, just the language thing is enough to make the comparison silly.

I mean thats the whole point of federalism and is why we have a Senate which represents states equally (no matter their size) at the same time the House represents people.

If something isn't popular enough to pass muster for the majority of people and the majority of states, it should stay a state law instead of a federal one.
