Is this guy as good as he seems?
Possibly he will change, but his record is not as good as you might expect. His earlier position was, evidently, that the immigrants deserved more welfare goodies. A few sources have said that was his position before the riots began.
When he called the rioters "racailles," I think his point was very different from what it has been made out to be. He was not saying that all the immigrants are scum. He was saying that the rioters were not Muslim fanatics or ordinary immigrants, but young thugs on a spree. In other words, his purpose was to exonerate Islam. The problem is not that they are Muslims but that they are thugs. But the other French politicians and media took his words as a wonderful opportunity to paint him as a fascist pig, and have been playing that note ever since.
In other words, I wouldn't build him up to be a resolute hero who would defend the West, because if he takes power I think we may be disappointed.
