While Macron hopes to obtain a comfortable majority and lead in the next round of voting, this is far away from reality. Mélenchon and his coalition's success have highlighted a clear message that France is not happy with the path that Macron and his party have been leading France down.
Macron's re-election has made him the first French president in two decades to win a second term. This is a clear indication of the positive work he's done for France. Though perhaps painful and against the will of the left-wing parties and activists, the reforms he's initiated are paying off. He must stay the course to enable France to prosper again.
If Macron's party is unable to reach a majority this would be a major setback for the French President. This could end up in messy, bill-by-bill deals with differing parties in parliament, with no party able to implement a true direction in policy. Such a development would be detrimental to France and French politics.
