While I agree with your overall argument regarding the overflow of issues and ignorance of their particulars, I have to disagree with your view on abstinence from voting being some sort of error prevention. By that measure, there is a right and wrong, then inherently, whether you vote or not, allowing the “wrong” choice to be made is an “error”.
I don't think they're saying the wrong choice is a particular candidate. The wrong choice is mistakenly voting for someone who doesn't actually represent you because you were ignorant of the candidate's stances or history.
