French presidential elections take place in two rounds - deux tours.
In the first round all the candidates are put forward and if anyone gets over 50% of the vote, then he elected.
However it is quite common for nobody to have over 50%, in which case the two front runners of the first round go into the second round, and the winner of that round wins.
Nicolas Sarkozy, who I miss greatly, has befuddled the minds of many people by speaking of those who vote for the FNPS - the Front National Parti Socialiste.
He has since explained himself, saying that when people vote for the Front National in the first round and give that party a good percentage they provoke a backlash which results in people voting socialist in the second round.
I think he is probably right, though he's been perhaps just a bit too creative, cryptic even, in his description as FNPS
