How the Filibuster Killed Accountability in Congress - Jacob S. Hacker, Political scientist at Yale

Interesting article: "Accountability suffers when a united minority party can kill popular ideas without leaving a mark. The upshot is that party accountability in the American system mostly centers on the president. Even in midterm elections, when the president isn’t on the ballot, dissatisfied voters tend to punish the president’s party at the polls." but, "a strikingly large share of voters struggle to identify their representatives in Congress, or even which party controls the House or the Senate.  In this context, voters are unlikely to punish a minority party wielding the filibuster—and, indeed, are far more likely to punish a president and a president’s party for policy failures caused by the filibuster, even if it is wielded by the other party.
