Before answering, please bear in mind that I’m asking about the candidate you are actually planning to vote for–not an abstract candidate, and certainly not a candidate your already oppose. For instance: I’d only vote for Ben Carson if he were running against the Joker, so even if it were shown to be true that he lied his ass off in hi autobiography, I am disqualified from giving that reason.
And another thing. I prefer that we talk about things your candidate has already been accused off, not some outrageous hypothetical. Again using myself as an example: I’m planning to vote for Secretary Clinton. Now I could say that, if she were proven to be an accomplice in Bill Cosby’s rapes, I’d become a Sanders supporter – but of course, not even Rush Limbaugh has accused her of that. But while I don’t care about her tolerating her husband’s infidelities, if it was proven to me that (a) Bill Clinton had actually committed a rape, and (b) Sec. Clinton had participated in a cover-up of that fact, I’d switch candidates.
There, the housekeeping’s out of the way, so I’ll recapitulate the question.
Americans, please think of the presidential candidate your are currently intending to vote for. What extant accusation against that person, if proved true, would cost him or her your support?
