What could the USA do in order to make a multi-party system more viable?
Obviously having only 2 parties doesn't work, because you aren't going to agree with most of their policies--hell, most people vote against the party they don't want more than for the party they do want.
I think this would require a change in culture. People would need to start supporting candidates based on their policies rather than based on chances of winning.
Another thing to consider is the fact that the people will never be fully satisfied with any party to the fullest extent; there will always be faults based upon different views... there's no way to eliminate that. A multi-party system would cause more confusion than what it's actually worth. It's quite unfortunate.
Of course, but you were suggesting (or seemed to be suggesting) that the US has taken a more liberal view, which I may agree with if it weren't for arguments such as gun rights; a conservative view which most democrats fight for. The US is more moderate than anything.
Would we really want a multi-party system in the first place? Sure, a two-party system has plenty of downfalls. But, it does force candidates to moderate somewhat, representing a broad range of issues. Imagine if we had multiple parties, each dedicated to only one or two issues and not caring much about anything else.
