Not sure his declaration is really news. I don't think anyone believes that the Supreme Court is nonpartisan at this point.
What seems odd is that more than 4 months away from the election he either just declared that he either doesn't care about ethics, or he doesn't actually want to rule on any of the cases that he feels strongly about.
"I am against voter ID cards," Megna's statement said. "I am against repealing same day registration, which largely prevents African-Americans, Hispanics and other minorities from registering at the polls on election day . . . As a Supreme Court Justice, if a voter suppression case were to come before the court, I would vote against suppressing the vote."
The state's judicial ethics code says sitting judges and judicial candidates must not make "pledges, promises or commitments that are inconsistent with the impartial performance of the adjudicative duties of the office" for matters that are before the court or likely to come before the court.
Granted a lack of ethics doesn't seem to be an issue in the court currently, but this clown doesn't seem to be turning things in a better direction.
