Muslims preoccupy Jennifer Troin.
"I'm worried about my nieces having to wear the veil," said the soft-spoken 29-year-old.
This fear has helped propel the young mother to the far-right of the political spectrum ahead of Sunday's key presidential election — and into the arms of the hard-line National Front party.

Troin sells children's clothes at a store in Cogolin, a town of 11,000 a few miles from the jet-set resorts of the French Riviera. In 2014, Cogolin became one of a handful of communities nationwide to elect mayors from the National Front, which is also known by the acronym FN.
Troin told NBC News that it wasn't just the FN's stance on Islam and immigration that attracted her, but also the party's populist take on the economy.
But most of all, it was the party's charismatic leader, Marine Le Pen, who captured Troin's loyalty.
"She fights for women's rights against Islam," she said. "I vote because of Marine."
Troin is part of a quiet army of female National Front supporters, who could well tip the balance of this weekend's election and give the presidency to the hard-right.
Last month's first-round vote was close with with Le Pen polling 21.5 percent of the vote and centrist Emmanuel Macron nudging his way ahead on 23.8 percent.
An FN victory would rewrite the continent's political playbook, given the party's pledge to take France out of the European Union. Were it to win, it would not have been an easy ride for a movement that previously peaked in 2002 when founder Jean Marie Le Pen — Marine Le Pen's father — reached the second and final round of the presidential election.
French voters flocked to the polls in the runoff to ensure Le Pen did not win, instead electing former President Jacques Chirac with a resounding 78 percent of the vote. Most pollsters expect a similar outcome in Sunday's second-round vote, predicting moderate voters to rally once again to shut out the FN.
But few doubt that the party's anti-immigrant and anti-establishment platform is resonating.
The Front's anti-Islamic message is especially potent in France, whose 4.7 million Muslims make up around 7.5 percent of the population. Islamist militant attacks have killed more than 230 people over two years and plunged the country into a long-term state of emergency.
This anxiety deepened on the eve of the first round after a gunman ambushed three Parisian police officers on the Champs-Elysees late Thursday, killing one and wounding two others. ISIS claimed responsibility for the shooting and French President Francois Hollande said it was likely a terrorist attack.
Meanwhile, the FN's influence has spread from its heartlands along the Mediterranean coast and in the rust-belt north, into rural "forgotten" France.
