I think the implication people may be talking about is that the above statement really is saying "a track record", not a known one. If that's the case, I posit that there is little rationality other than familiarity with a name, since it is otherwise meaningless and completely divorced from any results. (Though, I do concede the possible rationale being: "no catastrophe has occurred yet, so I might as well vote for the incumbent" [the ol' if it ain't totally destroyed, don't fix it line of reasoning].)
