I don't think Jack stands for anything or anyone....pure speculation....Jack seems to march to his own drummer...and probably could care less one way or the other.... though I'll bet he thinks Lesbo's like Ethridge pounding out their opinions are probably full of hot air.....
I think this is like with Clint Eastwood a few weeks back.
Jack is so set in his carreer, he has no need to spout liberal talking points to get a camera in his face. He doesn't need the publicity.
I agree with you, but I think it's because he has too much of an ego to stand for anyone else.
