"Textualist" is how Scalia portrayed himself, but if you look at Shelby County vs Holder, where the Supreme Court struck down most of the Voting Rights Act, Scalia's arguments basically came down to the idea that he was a mind-reader about what Congress really wanted to do, but was not politically able to do, never mind the text. Other times, he disregarded the clear intent of the lawmakers in favor of the strict textual reading. But he was hardly consistent. He was a textualist when the text favored him, he ignored it when it didn't. And maybe that's not unique to him - I'm not saying he was unique in that respect, but let's not pretend he was intellectually consistent.
In the end, he was a Republican justice. Nothing more, nothing less.
