AFAIK there is a significant (>=5%) chance that the election night totals will show a conclusive win for the incumbent, but the eventual complete tally will show the opposite. This has the potential to cause a lot of confusion in the immediate aftermath of election night. Whether there will be undemocratic moves by the incumbent or otherwise in the time between election night and the final count is obviously a matter of speculation, but given the mercurial temper of the country I worry about how the nation at large will react to such confusion.
