I thought about this in response to a comment someone made and postured a position in which the RNC and DNC are really just two monopoly companies at this point (link). I know there's protection for political parties, but is that what these really are now with how they're structured (kinda like they're ticketmaster/livenation for politicians at this point)? I couldn't find an easy answer and trying to dive deeper keeps pulling up irrelevant articles.
In the link comment I provided I did state it was a far off miracle. But, my focus was less on 3rd parties or electoral reform, it was directly related to the "National Committees" that exists. I'm all for state parties, reminds me of when Bell was split into it's different areas. But on a national level I wonder if it can be argued that it's so far removed from focusing on "political ideologies of it's group" to becoming a service provider for selected candidates. You could look at the committee's structures, are they even following their own political ideologies, what type of controlling power they have, etc etc.
