CMV: A 2 party system is the best political model for the US

I'm a moderate republican from the US who's never been too political, but after talking with a lot of people, I'm more convinced than ever that a 2 party system is best for the US. I want to be wrong, but I need you to convince me otherwise.<br><br>This is a US-centric post, so things like "it's not like this in my country" aren't really relevant.<br><br>Edit: i didn't know how unstable the comments would be - if you want to reply to a comment but it's been deleted, or if you can't post a top level comment, try sending me a message and I'll forward it to the comments so it can be replied to. I'll be doing this until the mod approves the post again.
