Key metric: Political Polarization Index

As a social scientist, I analyze that this article highlights the increasing political polarization in the New York mayoral race. The frontrunner Mamdani's focus on attacking Trump, a national figure, rather than local issues, suggests a strategy to galvanize Democratic voters by tapping into anti-Trump sentiment. Meanwhile, Cuomo's attacks on Mamdani indicate intra-party conflict, which could further divide the electorate. This dynamic is likely to increase the Political Polarization Index, as it emphasizes partisan divisions over local governance issues.
