@eal This is only the first round where the two candidates getting the most votes are qualified for the second round (unless one get the majority on the first round, but that never happens on the presidential election).

However, the last polls before the election show that they are 4 candidates that could be qualified (all around 20%, and all inside the margin error). In France, the first estimations of the results are given at 20:00 CEST (18:00 UTC).
