Or, maybe I should have asked: Have the Republicans on the court become less ideological?
|Justice||Same-Party Agreement, %||Opposite-Party Agreement, %||Propensity to Same-Party Agreement|
The numbers in the second and third columns are averages derived from Scotusblog (scroll down to the bottom). The last column is the second column divided by the third, so >1 means greater agreement with co-partisans.
Roberts and Kennedy are more likely to agree with the Democrats than with the other Republicans. I don’t think this has happened before. Last year, Roberts agreed with his co-partisans 88.8% of the time, and his opposite-partisans 81% of the time. For Kennedy, it was 86.8% and 82.25%. The Democrats and Thomas follow the ideologically polarized pattern of prior years.
