The country has sorted itself ideologically into the two political parties, and those partisan attachments have hardened in recent years. It will take an extraordinary event and act of leadership to break this partisan divide. I thought 9/11 might provide such an opportunity, but it was not seized.

Thomas E. Mann’s quote, “The country has sorted itself ideologically into the two political parties, and those partisan attachments have hardened in recent years. It will take an extraordinary event and act of leadership to break this partisan divide. I thought 9/11 might provide such an opportunity, but it was not seized,” reflects on the deepening polarization in American politics. He observes that Americans have increasingly aligned themselves strictly along the lines of the two major political parties, making cooperation and compromise far more difficult.

The meaning of this quote lies in its warning about the dangers of entrenched partisanship. Mann emphasizes that breaking such a divide requires exceptional leadership—leadership capable of rising above party loyalty to unify the nation around shared goals. While the 9/11 attacks created a moment when unity seemed possible, he laments that the chance to overcome the partisan rift was ultimately missed, allowing political divisions to continue hardening.

The origin of this perspective comes from Mann’s work as a political scientist and senior fellow at the Brookings Institution, where he has long studied Congress and American governance. Alongside Norman Ornstein, he has written extensively on the rise of polarization, gridlock, and the dysfunction of the U.S. political system. His analysis reflects decades of observing how ideological sorting and partisan loyalty reshaped the balance of power and cooperation in Washington.

Ultimately, Mann’s words serve as both diagnosis and caution. They highlight how deeply entrenched partisan divides undermine effective governance and how only extraordinary leadership—paired with moments of national significance—can bridge the gap. His reflection on 9/11 underscores the missed opportunity for unity, reminding us how crucial it is for leaders to act decisively when history opens rare windows for reconciliation.
