Answer
The answer is 72.71%. In the 2019 Tunisian presidential runoff, Kais Saied secured a landslide victory, capturing an overwhelming 72.71% of the popular vote. His opponent, businessman Nabil Karoui, trailed far behind with only 27.29% of the votes. Saied's decisive win marked a significant moment in Tunisia's political history, as he emerged as an outsider candidate and successfully challenged the traditional political establishment.
