“I just don’t think he’s got yet the proven substance or experience to be the president,” Carter told PBS host Charlie Rose in a 2006 interview, when asked whether Obama’s effectiveness as a campaigner and enthusiasm he had generated on the campaign trail that year might make him a good presidential candidate this cycle.
Elsewhere in that interview, he added that he considered Al Gore the best-qualified presidential candidate, although if then-frontrunner Hillary Clinton was nominated, he would support her.
Carter has not explained spoken publicly about his decision to endorse Obama, but in earlier interviews has spoken approvingly of the response generated by the Illinois senator’s candidacy.
