France’s Presidential Election Hinges on Far-Left Voters

PARIS—The duel between President Emmanuel Macron and far-right leader Marine Le Pen in France’s presidential election this Sunday hinges on voters whose first choice to lead the nation was a far-left, pro-immigration anticapitalist.

Supporters of Jean-Luc Mélenchon hold the key in the runoff because the candidate’s third-place finish, with 22% of the vote, nearly qualified him for the final showdown. Ms. Le Pen got 23.2% and Mr. Macron received 27.9%.
