If she's losing by this much, it shows she probably has too much ground to win back if the election is this weekend.
In that vote of a few weeks ago, she was at 24%, Fillon who is a bit like her, had only 19% but they said Fillon could win the election.
It's not looking good for Le Pen. She losing by about 24 points. If she is to win, one would have to discount the poll as being totally wrong. Maybe.
In other words, if this poll is correct, she is going to take a thumping. Some of her ideas appeal but some of the others obviously are not popular.
