That is why I don't think that commenting on Kelo would represent "prejudice". The case has been decided. There is no more information available for consideration nor is there any information hidden. A nominee's decision on such a case is no more an impediment to future fairness than the decisions reached by those on the court.
But the commenter did not evaluate all of the evidence. When a justice looks at a case, they see the whole of the submitted evidence. Someone on the outside doesn't see near as much.
JMHO - I'm an engineer, not a lawyer.
Thanks for a reasoned response, BTW.
Besides, on a case that sharply and closely divided, there's always the chance that the Court will overrule the Kelo case. In either event, a potential Justice who expressed the opinion that he/she would uphold/reverse Kelo, would disqualify that Justice from serving on that future case.
Trust me, it's a huge no-no.
