I tried to get involved with the College Republican'ts at my university on several occasions, and I was blown off each time. They were more interested in getting involved in local elections, networking, and schmoozing with each and every Big Time Conservative (Ann Coulter, especially!) that came to our kkkampus.
Whenever the school had debates and "roundtable discussions", at the alumni house, I was the only Conservative to show up, most of the time. I thought it would be better if there was a greater representation of the "other" point of view; that it would allow for more spirited debate... (instead of just me slapping around professors who were completely unprepared for any form of opposition.)
Many CR clubs won't even go as far as inviting big name conservative speakers to campus. They want to stay on the down low. I think this is for two reasons...
1. Many CR's have political goals/jobs in mind, and the ones who don't are just too busy with everything else
2. The threat of the group losing sponsorship on campus if the club does anything too rash. (Ex-Disbandment by the university for conservative activism, harassment of group members (everything from verbal threats to lower/failing grades on papers, and harassment by University officials in general). Therefore, they don't want to generate controversy or invite big name speakers to campus.
