I certainly don't blame you for having that view, since evidence at a glance would support it. But justices aren't supposed to take "whims" into account at all. They do, but it isn't right. It isn't their job to be high and mighty presiders over the land. Their only job is to interpret an ancient traditionalist document for the sake of measuring current issues against it for the sake of ensuring the type of justice for all americans that the ancient document intends. It's mostly a game of semantics and context, so I don't really understand why you think there is an inherit pull to the left that just "is there." Perhaps you could elaborate. Because at the moment my interpretation- that the reason republican appointed justices occasionally rule against their own political priors, is because the semantics and contextualizing inherit to the job can unbiasadly lead that way, in the type of impartiality we all would hope for and expect in a judge. Meanwhile, no democrat appointee ever (or maybe seldomly) seems to do the job as intended, since they pick their political priors first and then just rule in ways that justify them, despite semantics and context. As though bought and paid for by politicians, or at the very least complete failures at impartiality.
Do you think that justices lean left "at that level," because like RGB herself, you feel like the left represents a superior path to which the future is ultimately beholden?
