Marine Le Pen’s actual popularity is undervalued, given that voters tend to underplay how far-right they are in polls, theorizes Michelle Caruso-Cabrera of CNBC. She adds that almost half of French voters were undecided about whom they would support once their candidate dropped out. Political correctness has made voters fearful of expressing their support for Le Pen, speculates Caruso-Cabrera. She argues that polls during the US election and the Brexit vote failed to account for similar factors and ended up incorrect.
