Carter's public persona is pretty much a fabrication too, according to a friend who was a secret service agent in the whitehouse during Carter's administration. He said that Carter was extremely aloof, never friendly at all, and often rude to service personnel. He said Carter's kids were absolute prettythangholes too - totally spoiled and very demanding and snotty.
Personally, I think Carter has gone off the deep end. He seems to be in a big hurry to try to rehabilitate his legacy by trashing other administrations. Forget his idiotic politics for a minute, his public expression of lack of respect and lack of support for a serving US President are unheard of for a past president. He has no sense of honor for the US Presidency, maybe because he wants to bring others down to his miserable level.
