By your standard, we should let the machines vote because that's a multiple choice question.
Voting is basically a popularity contest anyway. An objective thinking machine would have to be fed an objective question, like: "Which candidate has appealed to the politically active youth community with a tech-savvy hip message of 'change' "?
That being said, your solution does not improve humanity. It does not make the voters (or the students) better understand their world. It's just a bandaid to hide their ignorance.
