If you've never heard of a group called "Friends of Abe," don't feel bad. They do their best to keep a low profile. You would too, if you were a group of 1500 entertainment industry conservatives living behind enemy lines in Hollywood. With a membership roster that's a highly guarded secret, Friends of Abe (named as an Abe Lincoln riff on 'Friends of Bill' Clinton) has become a sort of underground network for right-leaning entertainers. Among the few names who have confirmed membership in the anti-establishment support group are Gary Sinise, Kelsey Grammer, and Jon Voight.
