Evidence: One of the main arguments for electoral college, is that  it is more functional as compared to popular vote. This can be maintained through proportional representation. Source 3 stated that while the reguar electoral college has a chance of failing, it is not as high of a chance as popular vote is. Proportional representation keeps this functionality that those who support normal electoral college hide behind. This is also been proven to work without a hitch. As previously mentioned, Source 1 stated that this for of electoral college is already in Maine and Nebraska. These states have proven that this form of electoral college works, thus proving that we should change to proportional representation in order to maintain the functionality of regular electoral college.
