She's in the entertainment business. No different than Rush Limbaugh, Sean Hannity, Glenn Beck, Mark Levine, Todd Schnitt, "Cigar" Dave, Ed Schultz, Phil Hendry, Stephanie Miller, Mike Malloy, and all of their ilk. These individuals may bash on each other from time to time, but they are well aware that they feed off of each other for ratings......and you wonder why there isn't a single person of that group that broadcasts politics right down the middle? They simply shill for whatever political candidate they want, with token criticism of their loyal party. Besides, their private beliefs more than likely are very different than what is portrayed in the media.
She is reportedly good friends with Bill Maher. That should be all you need to know anyways.
