Tomorrow is polling day. We have a general idea of what the results will be, but the details might still hold some surprises. Where are the surprises to be expected? We do not know what percentage of the electorate will go out to vote, and whether the campaigns to get people out to the polling stations have had any effect. We do not know how those who defined themselves as undecided in opinion polls will vote, if at all. We do not know how the votes will divide within each camp, and finally, we do not know how many votes will be lost to lists that will not pass the qualifying threshold – according to forecasts, their numbers are likely to be much greater than in past elections.
