>> A crucial task faces the winner, seeing a front is far right in next spring's presidential election. But it won't be Nicolas Sarkozy, the populist former president's come back dreams in tatters, after loosing some days Republican primary. After his defeat, Sarkozy throwing his weight behind his former Prime Minister, Francois Fillon, who unexpectedly sailed past another former PM, Alain Juppé, into the second round.
Juppé still got in, but came a distant second after a lack lustre campaign that failed to ignite even his supporters. Economically, Fillon is further to the right with market reform ambitions. Initial polls have him winning next Sunday's contest, and going on to face Marine Le Pen, the steely far right leader in the first round of the Presidential race next year.
France's ruling Socialist President, Francois Hollande, has such abysmal ratings, that many see the fight for his successor as a straight contest between the center and far right. Donald Trump's shock US win, has bolstered fears that Le Pen's National Front Party will ride the crest of anti-establishment, anti-immigration wave.
Unlike Trump though, if Le Pen gets through, she'll have to stand in a second round, where she's expected to falter.
