Some states also tie vehicle registration requirements to whether someone chooses the state as their civic home for voting. If she plans to vote absentee back in – I’m taking a stab that you’re in Washington? Then that sends one kind of message. If she decides to vote in WV while she’s living and studying there, it might send a different message. Do look into whether there are any implications from that decision (I know my New England state has some driver’s license and car registration requirements that kick in under some circumstances if students who came from another state choose to vote here).
And good luck to your D!
