Was Harry Blackmun A Liberal Or A Conservative Judge?

Resolved: Harry Blackmun was always a conservative.

Pro:
-He was appointed by Richard Nixon, and was a registered Republican (at least when he was appointed).
-He believed that true obscenity was not protected by the constitution.
-He supported the death penalty, albeit in a limited fashion, MOST of his tenure on the Supreme Court.
-He was always the one who said, he never changed, the court merely changed around him.

Con:
-He voted with the liberal bloc, on Roe v. Wade, and always supported a woman's right to choose, while on the court.
-He eventually came out against the death penalty. (I don't have a cite yet. But I recall, he called it a "failed experiment", or something like that.)
-Conservatives hated him.
-Republicans hated him.
-He was not "original intent" (the new litmus test of conservativism, at least now.)
-When he resigned, he was arguably the most liberal voice on the court (but see above comment, too.)

So I will leave it up to the rest of you to debate: Was Harry Blackmun a liberal, or a conservative (judge)?

I thank you all who take the time to reply.

 

Definitely not a consertive, as a true conservative would only operate according to the Constitution.
