These talks about campaign finance, they are a distraction, in my opinion, treating the symptoms and not looking for an actual cure. If the USA really wants to improve their government, and their country, we need Constitutional Reform.

I've read a few articles regarding this idea; in my opinion, the notion of dismantling our entire electoral system to unclear outcome seems WAY more the distraction than focusing on a politically and structurally viable option (i.e. beating back moneyed interest with stricter campaign finance laws, waiting for another SCOTUS judgement to reverse the last couple bad ones, even amending the constitution to specify the limits of free speech vis a vis political spending).

Even if it were reasonable to expect the U.S. legislature to essentially amend itself out of existence, proportional representation wouldn't really be such a hot idea.

Consider: while Sweden is no doubt a wonderful country, it's also geographically smaller and less diverse than the state of Alaska. Makes PR a whole lot more workable. And while the majority of representational democracies the world across have chosen PR as their way to govern, the majority of representational democracies are again smaller and less diverse than the U.S. How would you expect the U.S. to fare given its social, ethnic, religious, economic and cultural diversity? How many parties would make it to parliament? How would you expect them to work together in any sort of functional coalition? Off the top of my head, I could easily imagine a federal PR system immediately striating more or less down state lines, granting disproportionate amounts of power to the most populated states or regions to the vast detriment of smaller or less populous states/territories. Wouldn't that be frustrating.

Our two party system isn't perfect, but in a nation as big and diverse as ours, there aren't really many workable alternatives. Given that this is the case, it makes perfect sense to chip away at the legislative mechanisms empowering moneyed interest to influence electoral outcome.
