The French have reelected Emmanuel Macron as their president, but the race was tighter than five years ago, when the same two candidates — Macron and far-right challenger Marine Le Pen — reached the run-off vote.

Macron will now need to shift his policies and ways — or else, France's far right might as well rise to power one day.

When he stepped onto the stage on Sunday night, Macron sounded not only glad and relieved, but also humble.

"I know that many of my compatriots have voted for me not because they support my ideas but because they want to block the far right from getting to power," he said. "This vote places a responsibility on me," Macron added.

Many voted for Macron despite his style and his program

Voters chose him despite his market-oriented reforms many of the French are opposed to — such as the liberalization of the labor market and the reform of the public rail company SNCF.

He was reelected although he did not manage to address the deep-rooted anger of the so-called yellow vests quickly enough or find a way to soothe their anxiety. These protesters blocked France's streets and roundabouts for months asking for more social justice.

Macron got away with first commissioning and then scrapping a €48 billion ($51.85 billion) plan to improve life for those living in France's destitute suburbs. He also got away with not better including French citizens with an immigrant background.

Voters have given him a second chance even though he did not do more to fight global warming — notwithstanding his 2017 pledge to "make our planet great again" when then US President Donald Trump announced his country would leave the 2015 Paris Agreement on climate change. Several courts in France have since convicted the French government for failing to adequately address climate change and not reaching its targets to reduce greenhouse gas emissions.

The republican front has started to crumble

But Macron did pay the price for all these policies.

France's so-called republican front — democratic parties and voters standing together to block the far right from rising to power — has started to crumble.

At an anti-racism demonstration between the two rounds, protesters were up in arms about yet again seeing the far right reach the run-off presidential vote.

But they were also aghast they would again have to vote for a candidate who doesn't appeal to them.

"Marine Le Pen is threatening our rule of law, but that doesn't mean I will give my vote to Macron — he only implements right-wing policies," one protester in his twenties said, explaining that the French had already held their noses and voted for Macron in 2017.

He added that the current president hadn't done anything for young people — Macron reduced, for example, housing subsidies.

Many of the protesters were supporters of Jean-Luc Mélenchon, the far-left candidate who picked up 22% of the vote in round one. These were ballots that Macron desperately needed to win the run-off vote.

Macron needs to change if he wants to stop the far right from rising

Macron did manage to convince enough of Mélenchon's voters to keep him in power — or rather Le Pen out of power. But many begrudged having to support Macron.

They see him as a lofty, arrogant manager, who's disconnected from their day-to-day worries.

Some therefore even opted to abstain or vote for Le Pen — their priority was to block Macron from staying in power.

And it's far from certain that, presented with the same scenario five years down the road, those Mélenchon supporters who did vote for Macron would do so again.

That's why the president-reelect needs to urgently start implementing more left-wing and ecological measures. He needs to change his ways and show that he does understand the suffering of those feeling left behind, in order to give left-wing voters the feeling that Macron is an acceptable alternative.

The president indicated in his speech he'd do all this. Now, he needs to go through with it.

If he doesn't, that could lead to — or at least contribute to — the far right continuing to rise. What decides the next French presidential election could then not be "everything except for Macron" but "everything except for Le Pen."
