Faithless electors are good. -like that electors go against the popular vote because they can prevent a corrupt president. They may be able to have access to more information than the general public. Sure, they could be wrong and that’s a risk, but risks are inevitable. For example of an inevitable risk: say a candidate has most of the electoral votes, since most electoral voters vote for the majority vote of their state, instead of their own judgement. At the very least, most electors aren’t faithless, so if one faithless elector votes for another candidate than most of the electors, then their vote won’t really matter anymore.
