It also misunderstands the notion that parties in the United States represent a myriad of interests - never a monolithic block of opinion. That's why parties have the ability to change their platforms without dissolving.
Parties are essentially no more than loose alliances whose diverse memnbers temporarily agree about how to get certain things done. People who are shocked to find disagreement within their own party don't understand what parties are.
Thank you for elaborating on my thoughts. That certainly dewfines and identifies the folly and uselessness of confusing the means with the ends.
