Actually, I sort of give Jimmy Carter points on this type of thing. He had to deal with his brother billy being drunk all the time and saying and doing stupid things. One time he had been arrested or detained or something for literally pissing on one of the embassies. I mean literally. It was obvious that the press was going to rattle him bigtime and they did so at a press conference- expecting a big explanation from carter. But Carter just said "I dont agree with everything billy says and does but he is my brother and I love him." Boom. Next question. Where are you gonna go wit dat?
