I think it is more about the other canditates getting serious consideration rather than Niinistö having done badly. Everyone has been expecting him to run (as a favorite) for a long time: in the 2000 elections he declined despite doing very well on 'speculative polls' (*), he ran in 2006 and got to the 2nd round against the incumbent Halonen (Halonen: 46.3% Niinistö: 24.1%) and almost won (48.2%). In comparision the other candidates are 'minutemen', that is, that they'd run become clear much closer to the election. Also, even in the latest poll 30% did not name a candidate (undecided or declined to comment), the result of next Sunday's first round would seem more unpredictable than usual although there being a second round would seem virtually certain, with Niinistö still being an extremely strong favorite to win that.
Initially finding candidates to run against Niinistö seemed kind of hard due to his being such a strong favorite e.g. the PM of the previous government (-2011) and Centre Party leader Mari Kiviniemi declined despite being one of the strongest potential canditates (then again Centre took a severe beating in the 2011 parliamentary elections).
