failed president? >> well, most people as the get older the mellow a little bit. get a little less judgment. you've gotten more black and white, carl. kennedy could do no wrong and bush could do no right. >> kennedy did a lot wrong. and bush was great in africa. absolutely great. fabulous. >> i agree with that. he's now spending a lot of time on that. >> he ace real human teitarian. >> i don't think there's any question when historians look back george w. bush will be on the lower rungs of president. but i think he deserves some credit with a hyperpolarization he's kept his mouth shut about his successor. i think he's dealt with that with a grace that's very characteristic of the bush family. i think he made some serious errors, grievous misjudgements that for which his presidency is always going to be scorned in many ways by historians.
