Do you ever see interviews with abused women that stay with their husbands? The interviewer always has a list of horrible things that the husband has done to the wife. It's stuff like:
He constantly lies and then comes up with wild excuses for his behavior.
He hangs out with his creepy friends instead of working, or when he does work he's so incompetent that his friends have to cover for him
Before she met him, her life was good. When they met, he promised her the stars. Now that she's married to him, every part of her life has turned to shit. Her son is gone, she's lost her job and is about to lose her home.
And in the end, he's robbed her of her independence. She can no longer think for herself. She is scared all the time. Her friends are always showing her the facts to convince her that he's rotten, but she can't see it. He's brainwashed her. For her, abuse is the norm. She doesn't remember the way it used to be.
That is the way I see most Bush supporters.
