Shows up as "Member Alert" on caller ID. If you call back, you'll get a rather lengthy message about the College Republican National Committee along with three options. If you want to be deleted from their caller list, press #3. I can't say for certain whether they respect the do not call request.
Called back and pressed option 3 to get on the "Do Not Call List." Thanks to everyone who mentioned this. I'm sick of these calls. FYI--I didn't have to listen to the entire intro/message. Pressed 3 almost immediately and got to input my request.
