Well, there are some interesting things about voting, from what I have read. First, in the beginning, ONLY male property owners could vote, but that had NO racial restrictions (which is a basis for folks seeming to need property to be registered), but those conditions have been modified by later amendments and laws.
Second, and I'm not certain about this, but some of the basic voting rights may be federal and others state. For example, some states have a timed residency requirement before being eligible to vote, so if one moves at the wrong time of year, one may not be eligible to vote, even in a federal election, unless perhaps special arrangements are made. As I recall it, when my ex-wife moved from Florida to another state, after consulting with both states, she absentee-voted in FL but had to promise not to vote for state and local candidates.
As to which particular issues and candidates are valid (If I am claiming domicile in a state but hardly ever there, I am still affected by many state issues like taxation, voting rights, vehicle registration
, and representation in both state and federal government. And even perhaps in local government, as the folks in Livingston TX found out when their right to register to vote was challenged.
I strongly suspect that when enough FullTimers are affected by voting restrictions, they will band together and work on it, just as some groups have taken up the banner for homeless voting rights. Since the states control the registration
process, and there are a lot of them, the voting rights for FTs efforts will have to be case by case.
BTW, I believe the Florida double-vote problem is more likely linked to condo owners rather than FTs because they are the ones with more vested interests in local governments.
