With regards to college students voting while away from college, I'd like to see some advocacy organization take up the mission to have all these "citizens" petition their respective schools to be refunded the excess charged for them being out-of-state students. Upon registration, the students have declared their residency within the state. It is unfair to charge documented new-citizens more than natural-born citizens.
Also, as declared citizens of another state, their parents back home should be disallowed the benefit of claiming them a dependents on their tax returns. How can one have a resident of another state as a dependent?
