•To assess presidential performance in the U.S. Supreme Court, we created a dataset of cases of concern to the President. The dataset covers Presidents Franklin D. Roosevelt through Barack Obama (1932-2015 terms), which amounts to 84 Court terms and 13 Presidents.

•Three findings emerge from the raw data.

    1. Presidents prevailed in nearly two-thirds of their cases; and captured over 60% of all votes cast.
    2. Obama’s win rate of just 50.5% is significantly lower than the average win rate and, in fact, the lowest in our dataset.
    3. A few commentators have noticed Obama’s problems in the Court, attributing them to Obama himself. But because our data show a downward secular trend in presidential success ever since the Reagan years, it may be that the Obama administration is just the latest victim of a Court that has gradually been losing confidence in the executive branch.
