I travel a lot, I spend 50% of time at home in city A, 25% in city B and 25% in city C. Often when I travel it’s election time in some locality. Once in a while it’s an issue I have a strong opinion on, and I spent a lot of time in that city so I understand the issue. I’d love to be able to split my voting power by where I spend my time and offer 25% of a vote to city B’s impactful referendum. Instead I’m forced to pick only one city to call home even though I feel a sense of being at home in multiple places.

I think voting should be about where you physically are and where you spend your time.

What about people who don't pay tax because they don't earn enough. Should they be allowed to vote?

They still owe taxes, it's just that some years their obligation is $0.

Edit: also there are things like fuel and sales tax that almost everyone owes, even if they don't have to pay income tax.

I don’t think I should be eligible to vote in every city, state or country I’ve paid sales taxes in over a year.
