Yeah the whole thing is really becoming a meta-commentary on the entire US political system. If it weren't so bizarre and dangerous, it would be really fascinating to watch (speaking as an American). On some level, many are subconsciously realizing the majority of both parties represent essentially the same geopolitical worldview that neither left nor right really agree with anymore (for different reasons). If this were a different country I'd predict a major political realignment on the horizon, but given how ingrained the respective neo-con/liberal ideologies are in the political infrastructure here ... I just don't see it as likely without something catastrophic happening to force the issue.
