You gotta be careful what you allow.....if being a 'properety owner' is all that is required, rich folks can end up voting in many localities.....

...and when the Supreme Court gives corporations ALL the rights of individuals, it will be 'interesting', hmmmm?

seems to me that a few years residence as a citizen is perfectly reasonable to be sure voting is taken seriously and that the person(s) are genuinely part of the community.
