After reading https://svenska.yle.fi/artikel/2017/06/13/ett-dygn-av-regeringskris-detta-har-hant I have to wonder, is Niinistö a super common Finnish name, or only a super common name among politicians? :-)

One President, one party chairman and one MP. Any relation? Would be interesting, as I think all three are in different parties.
