Ideological difference are not partisanship. Partisanship means you adhere to what the "party" wants, regardless of ideology. Ideological difference have always existed on the Court and are expected to reflect the varying ideologies of Presidents who appoint the Justices. There's nothing wrong with ideological difference. There is a lot wrong with partisanship.
As for the Court being capable of anything, I haven't seen much evidence for that kind of alarmism. One of the most egregious cases to be decided in some time was Kelo and the conservatives on the Court (plus O'Connor) got that one right.
Actually, I hate the result in Kelo. But it was consistent with all the zoning decisions since Euclid.
Interestingly, the one decision that was unanimous recently had to do with the way political parties in NY pick their judicial candidates. In that regard, the court agreed that politicos can pick anyone they want to put on their tickets.
You can call it "ideology" or partisanship, but in theory a Justice is supposed to be apolitical once he or she is appointed. It's the reason for the lifetime appointments. I'd also say it's pretty partisan when a justice who goes duckhunting with someone who will benefit from the results of a litigation won't recuse himself.
