I’ve actually had leftists argue that non-citizens/illegals should vote because they have a stake in the outcome of elections.
I have heard that argument as well, but I reject it, of course. If these non-citizen/illegals want to vote, they can become legal citizens first!
I’ve known a couple people here illegally claiming that they should have the right to vote because the outcome of the US elections affects the world. One of them claimed that he didn’t want to be a US citizen though as he liked to travel and he wouldn’t feel comfortable traveling on a US passport.
