Not that much of a mauling by FN standards, when her father reached the 2nd round in 2002 he got 18%, that's a serious improvement of the party's result.
In line with her being (at least publicly) less extreme than her father
34% is way too much for a fascist like Le Pen.
Her vote percentage has hardly gone up since the first round.
7.6M vs 11M... That's +45%.
Say what? She went from 21% to 34, that's a 60% increase.
Of course, this is a run-off, so even comparing them without some sort of normalization isn't enlightening.
64 to 34 in a popular vote is a landslide. If this was happening in a third world country, media would be calling it "obviously manipulated". Such numbers are unheard of.
