I think there are problems with both of these. For yours, why is Clinton Truman when Reagan/Bush are FDR? Reagan/Bush/Clinton as FDR/Truman/Eisenhower is actually a pretty good analogy, and I've long thought of Clinton as the Democratic Eisenhower. For the one in the link, I don't see what is particularly "disjunctive" about Carter as compared to other Dems at the time.
Mostly that he ran as an outsider who didn't have the stink of Watergate anywhere near him.
Obama and Clinton ran as fresh faced outsiders too, though. There've been "who said it" games picking from speeches from the 76/92/08 campaigns and they're pretty much indistinguishable at times. I don't see him as at all analogous to Trump in terms of being a departure.
