Question

why the declaration of the election result became earlier?​

Answer 1

Answer:

If no candidate receives a majority of the electoral vote (at least 270), the President is determined by the rules outlined by the Twelfth Amendment. Specifically, the selection of President would then be decided by a contingent election in a ballot of the House of Representatives.

Answer 2

Anders Fogh Rasmussen explained that the elections were called early in order to allow the parliament to work on important upcoming topics without being distracted by a future election.
