The article leans slightly left, focusing more on Democratic perspectives and strategies. While it does present some Republican viewpoints, the overall framing is more sympathetic to Democratic concerns about preserving democracy.

Key metric: Democratic Institutional Strength

As a social scientist, I analyze that this article highlights a significant shift in Democratic strategy in response to perceived threats to democratic institutions. The Democrats' adoption of more aggressive tactics, exemplified by Newsom's redistricting plan, indicates a departure from traditional approaches. This shift poses potential risks to democratic norms but is framed as a necessary response to Republican actions. The involvement of high-profile figures like Obama suggests a growing concern within the party about the effectiveness of conventional methods in preserving democratic institutions. This tactical evolution could have long-term implications for political norms and the stability of democratic processes in the US.
