You obviously know very little about Sarkozy, and even less about French politics. You definitely know very little about Le Pen, père et fille except they hate all foreigners.
The Le Pens also hate America, Americans, Israel, free markets, and capitalism. They do not believe in liberty, they believe in the tyranny of the State over the individual. They are not Conservatives as we Americans are. They are neo-fascist, anti-Semitic, isolationists. They are closer to Nazis and neo-Nazi National Socialism and communism than they are to conservatism.
Marine Le Pen, like her father, is authentic. She speaks the truth, especially about such things as immigration, the European Union, and Islam. Calling Le Pen, "neo-fascist, anti-Semitic, isolationists...closer to Nazis and neo-Nazi National Socialism and communism than they are to conservatism" is the usual crap elite Europeans do to demonize anyone on the right. The Left does the same thing here to conservatives and the Tea Party. The Soviets used to declare anyone who disagreed with the state view as insane and would put them in mental institutes and the Vietnamese communuists set up reeducation comments.
"Much as Friedrich Hayek caustically referred to socialists of all parties in the age of British muddy centrism shared between Labour and the Conservatives before the rise of Margaret Thatcher, one might see the choice of leading candidates in France as that between Eurofederalists of various parties. Neither Nicholas Sarkozy nor the likely victor Socialist François Hollande differ in their deference to ever-closer union. Much of their respective programmes must accordingly be discounted entirely as the outlines of an agenda they would never give themselves the liberty to execute."
Le Pen wants to exit the Euro. She wants to retain France's national identity, culture, and sovereignity. I have lived a total of 13 years in five European countries (not France however,) and I have witnessed firsthand the enervating effects of European socialism, which is now collapsing. And due to aging societies and reduced birthrates, the population of many countries will be declining significantly. Europe has benefitted from the US providing the security umbrella for 65 years allowing them to allocate more resources to welfare and social benefits. Most European countries devote 1% or less of their GDP to defense as the pressure grows to chose butter over guns. They are using up all of their seed corn to keep the welfare state treading water for a little longer.
And as Europe becomes more reliant on immigrants from the third world to keep their economies going, there is more and more friction between immigrants and the natives. Europe is not assimilating immigrants nor has it ever done a good job of doing so. Cameron, Sarkozy, and Merkel all say multiculturalism is dead.
Most of Europe is anti-Semitic, or at least anti Israel. The European perspective on Israel and the Palestinians is far different than in the US.
The right is rising all over Europe primarily due to immigration and the growing resentment that people are losing their culture and national identity. The EU has also sparked a reaction from countries that do not want to be governed from Brussels. The French pushed for the EU and were deluded enough to think that they would be controlling it. Instead, the Germans are calling the tune and everyone else has to dance to it. The upcoming Greek elections will probably shake the EU to its core if PASOK and Nea Dimokratia cannot even garner 50% of the vote between them.
Spain and Italy are shaky with immense problems. The ECB doesn't have enough money to bail them out. Most of Europe will be in a recession this year. If I were French, I would vote for Le Pen who is doing better than the rest among 18 to 24 year old voters. Sarkozy is trying like he did in 2007 to move right to get these votes. Le Pen will probably come in third. But the FN will grow in strength in the future.
