They are not "disenfranchising" the young. They are upholding law regarding residency and registering to vote. Dependent students are legal residents of the state where their supportive parents/guardians.
Students should vote absentee ballots for the county in which they are legal residents. Period. End of discussion.
Dependent college students are not legal residents of the couty in which they go to college unless their parents happen live in that county. They have no right to vote in a county in which they are not a resident.
Quit defending lawbreakers. We're not Dems!
