What Bernie Sanders told Zohran Mamdani about antisemitism and pushing back on Democratic leaders

As a social scientist focusing on key performance metrics of the United States, I would consider the most appropriate metric for this article to be "Political Polarization Index." This index measures the degree of ideological divide between political parties and within the Democratic Party itself.

Speculation on how this information might affect the Political Polarization Index:
The article suggests that Zohran Mamdani's victory and subsequent treatment by Democratic leadership could potentially increase political polarization. His democratic socialist stance and the reluctance of some Democratic leaders to embrace him indicate a growing divide within the party. This internal friction, coupled with Republican plans to use Mamdani as a "national foil," could lead to a higher Political Polarization Index score.
