It was Jefferson’s graciousness that was so appealing. He was never blunt or assertive as Adams could be, but subtle, serene by all appearances, always polite, soft-spoken, and diplomatic, if somewhat remote. With Adams there was seldom a doubt about what he meant by what he said. With Jefferson there was nearly always a slight air of ambiguity. In private conversation Jefferson “sparkled.” But in Congress, like Franklin, he scarcely said a word, and if he did, it was in a voice so weak as to be almost inaudible.
