That thought occurred to me, too. Yesterday there was an article about Trump supporters being kicked out of some “Republican” club in Manhattan, and I thought then that there should be some control over WHO EXACTLY is allowed to call themselves “Republican”.
Shouldn’t the GOP be able to revoke the use of their trademarks by people who are in opposition to the party’s official platform ? The RNC should be able to force name changes on clubs and revoke party membership from individuals, with a restraining order from using the terms “GOP” and “Republican”.
Curious if “GOP”, (R), and “Republican” would have to be trademarked, copyrighted, whatever to achieve such a goal as you suggest.
