Original draft or rewrite? Jefferson's initial work was considered too inflammatory by the other founders, and they stripped some of the objectionable language out of it. Jefferson always resented this and proceeded to show his original version to any visitors who happened to stay at his house, urging them to chose which of the manuscripts they thought better.
