Tad Devine, a former chief campaign strategist for Sen. Bernie Sanders, said the Democratic National Committee and Hillary Clinton sabotaged Sanders' 2016 presidential bid [1].

These allegations highlight ongoing tensions between the progressive wing of the Democratic Party and its established leadership. The claims suggest a coordinated effort to protect traditional power structures by suppressing insurgent candidates through institutional means.

Speaking at the C-SPAN Q&A Podcast studio in Washington, D.C., Devine described a system of deliberate interference. He said that Hillary Clinton, the DNC, and allied dark-money groups utilized dirty-trick tactics and mainstream-media bias to undermine the campaign [1, 2].

"The DNC and the Clinton campaign used dark‑money groups and coordinated media attacks to keep Bernie off the ballot," Devine said [1].

Devine said that the Democratic establishment sought to preserve the party's existing power dynamics and protect the candidacy of Hillary Clinton. According to Devine, this effort involved leveraging media influence to marginalize the Sanders campaign [1, 2].

A CNN correspondent said that the party's elite were terrified of a Sanders insurgency and engineered a series of sabotage moves [2]. These actions were aimed at ensuring the 2016 [1] primary did not shift too far toward the progressive left.

The interview, published earlier this month, brings renewed attention to the internal conflicts of the 2016 primary cycle. Devine's account emphasizes a pattern of coordination between official party organs and external financial interests to maintain the status quo [1, 2].

The DNC and the Clinton campaign used dark‑money groups and coordinated media attacks to keep Bernie off the ballot.

The allegations by Tad Devine reflect a persistent narrative of institutional bias within the U.S. Democratic Party. By claiming that dark-money groups and the DNC coordinated to suppress a progressive candidate, Devine underscores the conflict between grassroots movements and the party's formal leadership. This discourse often informs current debates over primary reform and the influence of superdelegates and party elites in nominating presidential candidates.
