Should College students have to vote in their home districts?

I have some conservative friends who live in the People’s Republic of Berkeley, California, who complain that their city is run by extreme liberals because of the large number of college students, from other districts, who vote where they live while going to the University.
Should those students have to vote in their home districts?
Should they be allowed to control elections in a town where they have no long term obligation?
I don’t know the answer here, and look forward to input.
