Sure they have. Heck, you've even seen it. As I noted previously it appears in (a) the fact that he PUBLICLY STATED his support for it and (b) that Congress took up a bill on it after that statement of support.
And yet none of this 'quality reading material' seems to have any evidence that Davis paid more than lip-service to the establishment of a supreme court.
False. Practically any history of the matter identifies the Congress' inaction on the courts as a way of blocking Davis' desire to increase his power.
What you have noted is that Davis PUBLICLY STATED his support for it and then did ABSOLUTELY NOTHING to put those empty words into actions. He let the matter die in the confederate senate, probably because he had a rebellion to run and a supreme court would have gotten in his way.
False.
True. None of them indicate any actions that Davis took to get congress to staff the court. Davis doesn't bemoan the fact in his books, in fact he doesn't mention it. Why should he comment on something of so little importance to him?
