According to polls from the Cevipof, up to 32 per cent of French people will not vote for either Ms Le Pen or the Centrist Emmanuel Macron, which would be the highest number ever.
They will “vote blanc”, which is a protest vote when people go to the polling station to vote but give in a blank ballot paper.
One activist, Rudolph, has described the prudential election as a choice between “two devils: fascism and finance”.
He is one of the many people who will not be voting on Sunday and would “rather take the fight to the streets”.
According to an Ifop poll, which is based on 100 voters for each candidate, more than a third of people who voted for Jean-Luc Melenchon and Nicolas Dupont-Aignan in the first round will abstain on Sunday’s crunch election.
For the ‘Gaullist’ Jean-Luc Melenchon, 50 per cent of his voters will opt for Emmanuel Macron, 13 per cent will vote for Ms Le Pen and 37 per cent will abstain.
The right-wing Dupont-Aignan is Ms Le Pen’s nominee for prime minister.
Three quarters of voters who supported the Socialist Benoit Hamon in the first round will vote for Mr Macron in the second round with 18 per cent abstaining and seven per cent planning to vote for Ms Le Pen.
A few people who voted for Ms Le Pen or Mr Macron in the first round have said that they will either abstain or even vote for their rival in the second round.
Despite the Front National candidate desperately vying for Francois Fillon’s Republican vote, just 30 per cent of his voters will support her with 44 per cent voting for Mr Macron and 26 per cent abstaining.
According to the poll, Ms Le Pen will pick up the majority of her second round votes from the voters who supported for Nicolas Dupont-Aignan.
Almost half, 47 per cent, of Mr Dupont-Aignan’s voters will vote for Ms Le Pen with 17 per cent supporting Mr Macron and 36 per cent abstaining.
When the two candidates were debating in the final television debate, the hashtag #sansmoile7mai, which means without me on May 7, was one of the top trends on Twitter.
Professor at Paris Ouest Nanterre University, Sylvain Crepon, said: “Le Pen may not win.
“But after this campaign, it is clear how divided the country is.”
At the Paris May Day protests, campaigners held banners with: “Plague or cholera: we don’t want either”, written on them.
