Hi all,
As a reminder, /r/AskHistorians exists to answer questions about historical events. We do not exist to talk about current events. I've already removed a couple of comments in this thread questioning the premise of the question -- that several CR chapters have been stripped of credentials.
If you're coming here to answer the question, please ignore that, as it's not an appropriate subject for discussion here.
Instead, what we can answer is the second part of the question:
Where and when did College Democrats and Republicans originate? When did they become politically active?
Thanks for understanding.
