There has always been a gentlemen's agreement that you register in your home state, unless you are unamerican and then you're inherently dangerous and we must be suspicious of you anyway.
Sometimes but not always. In the past, some people (though usually foreigners) have moved wherever the population is lowest. Strategic registration has always been a concept, though.
Since it seems like this is the thread to do it, can we also condemn the NM-AM for their strategic registration instead of just ganging up on the PU?
To my knowledge, the revolution's spatial distribution is largely the result of Pacificans feeling most drawn to the NM-AM.
