I haven't Googled CREW yet, but I'm thinking that maybe, just maybe, they are a Right Wing organization. Again, consider the source before you declare it as fact. I have absolutely no doubts about Charlie and Maxine, but the rest...not so sure.
P.S. I just cruised their site, and they seem like an Equal Opportunity watchdog at first glance. They also have some interesting information on the Boehner and Gov. Jindal of Louisiana.
