J'espére que non. :)
It would be the first time a National Front candidate goes to the 2nd round, though, if I'm not mistaken, and it could get very close.
I haven't been following it properly, and was surprised to notice that the Socialist Party candidate is not one of the front runners.
As it is, it's possible that none of the left wing candidates may go through to the 2nd round, and it could be a choice between the far-right and the right. I'd hope left-wing voters would go en masse for the right-wing candidate, but opinion polls suggest that is not the case, although it seems Fillon (righ wing) would have a clear victory.
It might be a better option than a left-wing party candidate who might not be as acceptable to right-wing voters as Le Pen.
