Well, it's tongue-in-cheek, but more than once I've thought abut the ability to move somewhere without moving there. Like, if I live in Oregon, there's nothing stopping me from going on vacation to another state for months out of the year. So why can't I "move" there without having to physically go there? I think about this in context of the red/blue voting divide. If a couple million people in safe blue states "move" to red states, then the Senate would be more representative of the population. Or even to counties across the same state to break up gerrymandering.
I'm sure it's illegal in a bevy of different ways, though.
