I think this commentary ignores what is probably the root cause of the "appearance" of political ideological alignment of a judge to political party.

The main alignment as displayed by the political senators and their line of questioning. It appears to me that the democrats are quite comfortable for judges to "NOT" follow the law and let judges become legislators and should unilaterally correct laws that the congress enacted that are lacking.

Additionally the alignment of "big business" is with the enactment of the laws by the congress. Convictions to FOLLOW what the law says makes the appearance of ideological alignment. Big business is with politics which writes the laws.

Correction of the courts lies with Congress to fix/change/update laws not with changing the judges. The judges, no matter what personal leanings are simply applying laws "as written" right or wrong unless usurped by higher law.
