As for the other question, one who dislikes the FN cannot be happy with those results. FN is settling everywhere, they are going to win something between 50 and 120 cantons, and that gives them proximity office holders who can then be credible candidates in next elections, especially the législatives. Not good.
No decent person should be happy, neither lefties nor mainstream right-wingers. I guess that the level of decency must not be so high among the UMP ranks. However, if I was a moderate among them I couldn't feel any reason to celebrate with the fascists at 25%.
