You may be correct. In more recent times it seems that an individual SC judge votes pretty much along their party lines (i.e. political leanings).
I would image a vote on if suicide is a Constitutional right would follow pretty much along the SC Justices political views.
In a way, probably. However, rather than political lines alone, I've found that the three basic categories I listed above fall pretty much within those political categories as well. As examples, and based solely on my opinion:
Scalia was a Textualist by his own admittance, although he also tended to lean toward Originalism at times as well.
Thomas is also, like Scalia was, a Textualist although he seems to be less of an originalist than Scalia was - as demonstrated by his opinion in McDonald v Chicago regarding the 14th Amendment's Privileges and Immunities Clause.
Ginsburg, Sotomayor, Kagen and Breyer, all tend to rule as Non-Originalists on most cases when ruling in favor of a positive position (such as what are defined as social justice positions in modern parlance), yet will from time to time place thoughts within their written opinion based on Originalist Intentionalism (defined below) if it helps to further their particular ruling when opining against rather than in favor of a position (as they tend to do with the 2nd Amendment rulings).
Roberts and Alito seem to me to be Originalists that vacillate between ruling as a Textualist or as an Intentionalist. I didn't discuss Intentionalsim in my earlier post because I feel it's a subcategory of Originalism. Although many feel that Textualism is a subcategory of Originalism as well, I feel Textualism is a completely separate category: An originalist who gives primary weight to the intentions of the Constitution's framers, members of it's proposing bodies, and it's ratifiers, is a Justice who could also be referred to as "an Intentionalist."
Kennedy tends to rule as an Textualist on personal rights and liberty issues, and a Non-Originalist on government powers granted by the Constitution to the Federal Government over the people - which is in many ways, a contradiction in thought and practice, but it allowed Kennedy to be the swing vote, or what some called the conscience of the court.
You can see from above, how the Progressives on the court align with the Non-Originalism thought process for the most part, and the Conservatives on the court align with Originalism and Textualism for the most part, with Kennedy moving between the two sides as he felt necessary.
Again, this is just my opinion. With no evidence other than that which is anecdotal in nature to substantiate my opinion.
