In a scenario where incumbent Francois Hollande is running along with former Economy Minister Emmanuel Macron, Fillon would win the first round with 32 percent of the vote against 22 percent for Le Pen and 8 percent for Hollande, according to a poll by Odoxa for France 2 television. In the run-off two weeks later, he would defeat Le Pen 71 percent to 20 percent, according to Bloomberg.
A Harris Interactive poll showed Fillon winning the first round with 26 percent support compared with 24 percent for Le Pen and 9 percent for either Hollande or Manuel Valls as leader of the Socialists. The same survey showed him winning against Le Pen in the second round 67 percent to 33 percent.
Odoxa surveyed 998 voters on Nov. 25. The poll has a margin of error of 2.5 percent. Harris surveyed 6,093 people on Nov. 27 without giving a margin of error.
