Yes, Ann is a Deadhead. There was a rumor that conservatives can't be cool.

Here's a sample from an interview with Jambands.com

Ann: I fondly remember seeing the Dead when I was at Cornell. We'd cover ourselves in purple Crisco and drink purple Kool-Aid mixed with grain alcohol and dance on the front yard. Wait – I think got the order reversed there: We'd drink purple Kool-Aid mixed with grain alcohol and then cover ourselves in purple Crisco – then the dancing. You probably had to be there to grasp how utterly fantastic this was.
