Rethinking Jimmy

What in the world? First, I thought Jimmy Carter was simply a Christian who didn't know how to do his job well, if he is a Christian at all. I spoke with some people, mature Christians who lived through his presidency, and they said Carter lied to them back then to gain their vote. I also read articles saying that he is a Christian and not a liar, but just didn't do what he was supposed to, that he was too weak. Now I'm more sure that he's just a nominal Christian and that he didn't think about the consequences of his decisions, mainly because of lack of knowledge.
