When it comes to judges, you can consider it pretty likely that the majority do, since the conservative "ideology" with regard to judges is that they shouldn't overrule the will of the people without a clear unambiguous constitutional reason. The Dems disagree, but they're afraid to say so publicly, so they hide behind weasel words like "extremist". The bare fact that they use that word doesn't mean you have to believe that it's even remotely true. All conservatives have to do is force the Democrats' hand, and the party's over for them. But this nomination represents a wholly unnecessary retreat from doing so.
But since it just ain't so, the founders had a plan to keep things in check, so let's just stick to it.
Part of the plan is for informed citizens to keep the pressure on their public servants, and so that's a plan that I'm highly in favor of sticking to.
