And the power house politician who is riding high in the polls has taken aim at Europe in yet another scathing analysis of its economic policies.
Mrs Le Pen, 48, is calling for the French to unite behind her to make her the first female "head of state” in the Republic of France.
And the former immigration lawyer is said to be winning voters every day thanks to her enthusiastic followers who are determined to shake up the establishment.
In a letter to her supporters, Mrs Le Pen says farmers are facing "terrible difficulties" as a result of the EU's failing Common Agricultural Policy.

The blonde firebrand right wing leader said that France's national identity is under threat and that she has a "duty to preserve it”.
She said: "I am struck by the enthusiasm and hope of the militants I meet.
"I thank you: each meeting is an additional motivation to move forward and continue to convince the French.
"On Monday, I went to Mont Saint-Michel, a high place of spirituality and wonder of French heritage.
Marine Le Pen is popular with the farming community
"I wanted to appeal to the gathering of all the French.
"The time is not for small political quarrels, France is in a serious situation that deserves that all unite for her.
"I wanted to highlight the seriousness of the stakes that are those of the presidential election facing the challenges of the world that comes.
"We must do everything possible to preserve our national identity, our way of life and our heritage.
"France is an inheritance that we have received from our parents and borrowed from our children; We have a duty to preserve it and develop its potential.
"We must not accept its denial and programmed stifling within the European Union.”
Member of the European Parliament Le Pen also visited the Paris International Agricultural Show known as the Salon de l'Agriculture and pledged her support.
She added: "I spent almost eleven hours at the Salon de l'Agriculture; it is with joy and interest that I meet farmers, breeders and all the professionals of the sector every year.
Mrs Le Pen is swamped with supporters wherever she goes
"I also note with concern the terrible difficulties that the peasants are courageously facing; The European Union is a real plague and the CAP is a perverse system that must be abolished in favour of a national system.
"It will be, in equal or even greater amount, much more just and effective.
"The very warm welcome I received was a great treat.
"It is because I am the only candidate to have a future project for our campaigns that I am the only one to be really welcome at this show and I intend to return next year to inaugurate it as head of The State!"
Mrs Le Pen also said that the French economy is in chaos and that she is determined to fix it.
She added: "I developed the economic program that I intend to implement as soon as I am elected head of state.
"France must find a true economic strategy.
"The state will be a fundamental actor in restoring the power of the French to their economy and to revive it by patriotism and intelligent protectionism.
"The project that I am carrying out is coherent and voluntarist, it is the best and the fastest way possible for France to return to prosperity".

And while her opponent Emmanuel Macron spent the week insulting Brexit voters after his trip to meet Theresa May, Le Pen instead went to a tiny village to ask for their support.
She added: "I went to Seine-et-Marne to meet the mayor of Vaudoué, a village of eight hundred inhabitants.
"The mayor formerly supported the Republicans but has had the courage and coherence to join the patriots and give me their sponsorship.
"We must give breath to the institutions that are at the heart of our local democracy: the commune and the department.
"While some of my opponents want to privilege the metropolises and to suppress a part of the departments for their benefit, I believe it is essential for the territorial balance to maintain the autonomy of the communes".
