A Norwedish guy just told.me he is nostalgic for a Norwedish union... is this a common political opinion?

They were ynited until '05 apparently: https://en.wikipedia.org/wiki/Dissolution_of_the_union_between_Norway_and_Sweden

I get that it's more of a nostalgic dream than a hard-headed practical policy. But if I did a poll would it be a popular opinion there?
