The consolation is that Sarkozy is probably one of the more sensible politicians in France outside of FN on immigration (unlike establishmentarians like Merkel in Germany and elsewhere in Europe, Sarkozy has acknowledged that African and Arab immigration to his country is a problem), and that he will have no choice but to give FN's views a hearing if he loses by a narrow margin.
“If he loses by a narrow margin” should be “If he wins by a narrow margin”
