@Holiday20310401,
To bias voting in a way that values one vote over another, destroys the purpose of voting. One could argue that in places like the United States that employ the electoral college system that the point of voting is destroyed anyway. The idea behind a popular vote is to derive the popular mandate this includes the uneducated.
Having said this, it is mostly the educated that vote already. In the united states anyway they are either the left leaning educated, or the right leaning educated, being that it is mostly a two party system. It often seems to the people who's party/ideal/platform is not in power that the other group is uneducated. Now, however, if you are refering to the divide between the academic - educated, versus the corporate - educated or the non-religious-educated versus the religious-educated, these most often divide down party lines as well.
Also if I am not mistaken, a preponderance of college educated people vote down a left leaning ticket, while those that are less than college educated tend to vote down a right leaning ticket. It would fall that the more skewed towards higher education that a vote is would mean a more left leaning ticket, which has the probability of disenfranchising the right leaning voters often, creating yet another form of elitism.
