Liberal vs conservative sororities

[californiagal01]

This is my first year and I haven't rushed yet. I'm quite liberal about social and political issues and have been told that sororities tend to be conservative. I don't think I would fit into a group where I'm surrounded by people who listen to Rush Limbaugh, members of the religious right, country music fans, or ditzy cheerleaders. I'm looking for some feedback on which organizations tend to be more liberal and which are conservative.
