Whose optics? Its only relevant to the people that would only vote for her. I'm no political strategist, but they'll have to undo the (untrue) opinion that she was in charge of the border, which is one of the Dem's primary losing issues right now. If the Republican's can pin that vision into swing voters minds, true or not, she stands no chance to win. I am unsure if that is a fair prediction but that is why I generally hope they can find someone else.

She was on the ticket, so the optics would be of pushing out a qualified, experienced, already-in-place vice president and woman of color because...reasons that are definitely not racist wink wink would be the Republican ad.
