The Associated Press, which most conservative pundits claim is irretrievably liberal, comes forward with a story that certainly confirms what most conservative court critics have alleged. Namely, that politics matter in what our robed masters decide.
The study looked at some 38 decisions various courts have rendered on Trump's travel ban on people from a handful of chaotic Muslim countries. The politics of the president appointing the judge tended to predict how each judge would decide.
Twenty-four of those decisions were decided by judges appointed by Democrats, of these 23 decided against the Republican President. Fourteen were decided by judges appointed by Republicans, 10 of the 14 decided in support of what the President had chosen to do.
My eyeball says those numbers demonstrate bias, what does your eye tell you? If you want to describe the same phenomenon in a more positive light, you'd say presidents choose to select as judge nominees people whose overall philosophy is like their own.
The numbers also demonstrate "judge shopping" on the part of those who favor unrestricted immigration, an unsurprising finding.
