Bruno Jeanbart, of the OpinionWay polling institute, said Le Pen had taken a "risk" because the remarks could associate her with her father, even though they "were not ambiguous".
Le Pen said Sunday on RTL radio "I don't think France is responsible for the Vel d'Hiv", in reference to the stadium where many thousands of Jews were rounded up on July 16 and 17, 1942, before being sent to Nazi death camps.
Le Pen has said repeatedly that France would leave the European Union under her leadership, while Melenchon has said he would pull the country out of North Atlantic Treaty Organisation. "It's not France", she told LCI television.
Speaking at a big rally in the southern port city of Marseille, veteran Communist-backed candidate Melenchon sounded full of confidence.
The French government has previously apologized for the role French authorities played in the round-up of 13,000 Jews at the Vel d'Hiv cycling track in 1942 at the behest of Nazi officers.

Le Pen later said in a statement she "considers that France and the Republic were in London" during wartime and "the Vichy regime wasn't France".
"The Vichy regime was not France", she said, adding however that this did not absolve those who participated in "the vile roundup of Vel d'Hiv and all the atrocities committed during that period".
Rival election candidates also criticized Le Pen.
French physicist Serge Galam, who predicted a Trump victory, claims that a Le Pen presidency is very likely because of her strong base of support versus lukewarm feelings that exist for the other potential runoff candidates. "It ... runs completely counter to the party's efforts and gives ammunition to all those who say that the National Front remains a party with extreme right militants and culture".
In 1995, more than 50 years after the fact, then president Jacques Chirac deemed that "the time had come to clearly recognise the fault of the collaborating French state, and no (subsequent leader) should contest it", Le Monde said.
Korea may be capable of sarin-loaded missile attack: Japan
A year later, the group was behind another sarin attack on the Tokyo subway which killed 13 people and injured 4,000 others. Mr Abe made his warning at a meeting of Japan's parliamentary diplomacy and defence committee, reported by broadcaster NHK.
Meanwhile, two of the outside contenders in France's presidential election, Francois Fillon and Jean-Luc Melenchon, whipped up support with mass rallies on Sunday, seeking a last-gasp boost ahead of an increasingly tight first voting round.
Of the rest of the candidates, the socialist Benoit Hamon experienced in recent days a notable setback and is below 10 percent, which leaves him practically out of the fight. The two-round presidential election is set for April 23 and May 7.
French presidential candidate Emmanuel Macron wants to hold discussions with USA social media groups about how to halt the spread of "Islamist propaganda".
Le Pen and Macron - dubbed the "fragile favourite" by the Journal de Dimanche - are neck-and neck but both have lost ground slightly and would win 23-24 per cent if the vote were held today. In this framework, she said French Jews should be banned from wearing kippahs in some public spheres to preserve equality and facilitate further bans on wearing Muslim religious clothing.
