Students should apply for postal registration for their home town.
In my opinion it's better that they shouldn't be eligible to vote somewhere where they are (statistically) unlikely to be living for the full future term of the candidates.
Yes, they might not end up living back where they came from either, but the fact that their families probably will, might prevent them from making protest votes?
Hey Bruce - what happened to no taxation without representation?
ETA due to Rich's post - in cases where the student does not have a permanent "home" ie family address, then of course their place of residence should be their college location. No-one of age should ever be denied the vote - many people in the past died to get the vote, its importance should never be under-estimated.
