Chart of the Day: The Supreme Court Over the Past 70 Years


Christopher Ingraham at Wonkblog pointed me to an interesting bit of data yesterday. It’s the Martin-Quinn measure of how the Supreme Court tilts over time, and apparently it’s widely accepted as reasonably accurate. Here it is for the entire postwar period:

There are two fascinating nuggets here:

  • Despite conservative kvetching, the Court has leaned conservative for all but seven years from 1946 to 2013. The seven years of the Warren Court are literally the only period in recent history during which the Court has been consistently liberal.
  • The Martin-Quinn measure depends on the votes of the median judge, which is Anthony Kennedy right now. This is what accounts for the Court’s recent shift to the left. According to his Martin-Quinn score, Kennedy has been getting steadily less conservative ever since he joined the Court, and over the past three years he’s become positively liberal:

I suppose this is old news to veteran court watchers, but it’s new to me. Has Kennedy really shifted that much over his career? And is he now generally left of center? If so, does this have anything to do with the effect of Sotomayor and Kagan joining the Court in 2009-10? It sure looks like it.

DOES IT FEEL LIKE POLITICS IS AT A BREAKING POINT?

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
