I think it's a bit disingenuous to assume partisanship on the basis of a <1 year voting record. That's a serious charge to levy against a judge, as it implies he/she is violating his/her judicial oath by failing to "administer justice without respect to persons, and do equal right to the poor and to the rich".
It's rather unfortunate that courts have become the foci of partisan politics. It reflect the reality that Congress has been effectively abdicating their duty as the ones who must write the law.
