You can’t just drive around and vote everywhere . You’ll need permanent residence.
EU citizens are allowed to live and work anywhere in EU, so by default they are also allowed to vote in their municipality where they live. info
I don’t know if the following applies everywhere, but where I live this also includes people from outside EU, if they are allowed to live here permanently.
National elections require citizenship.
It’s a slippery slope.
Sure, nobody likes the Russians right now, but it also applies to other immigrants and refugees from elsewhere.
In Denmark a right wing party suggested something similar. They know fully well that immigrants don’t vote for them, and they’d love nothing more than to remove their political representation and eventually remove them from our welfare too.
I’d definitely be wary of who and why they want to remove voting rights for certain tax payers.
