Proven, but not necessarily proven to be good. It's a lot more subjective than some are willing to admit. A lot of people are apparently willing to vote for a lot more abrasive and unstable candidate than to put up with 4 years of that "proven" record.So you have less difficulty arguing for evil then you have in accepting that Hillary Clinton has a proven track record.
We'll have to wait at least another decade for the dust to clear before deciding on "best" or "worst" status, though.
