As French voters head to the polls this Sunday in the first of what is expected to be a two-round presidential election, polls suggest far-right leader Marine Le Pen is zeroing in on incumbent President Emmanuel Macron.

Le Pen, who has worked to soften her image since the 2017 election and appeal to France’s moderate base, has seen a surge in support in recent weeks with one poll showing the two in a dead heat for the presidency in a potential runoff with Le Pen receiving 49% of the vote compared to Macron’s 51%, according to a YouGov and Datapraxis poll published Friday.
