Answer:
According to the article:
Myth:
- The ability of a consensus-building Justice to wield enormous influence on the court can wish away the court's ideological fractures.
Why it is a myth:
- The ideological differences on the high bench are too big to be bridged by personality.
- The Roberts Court has split predictably 5-4 on almost all the hot-button issues.
- The most powerful Justice is Anthony Kennedy because five votes beat four, and he is the swing vote on almost every issue.
- The most influential Justice is Antonin Scalia, who has succeeded in profoundly changing the court's entire methodology for interpreting statutes and has made respectable a mode of conservative constitutional interpretation - "originalism" - that would likely be moribund without him.
The author makes the point about the myth by using the example of Chief Justice John Roberts. Despite entering the court with high expectations that his interpersonal skills would create greater collegiality, the ideological differences among the Justices proved too big to be bridged by personality.
The Roberts Court has continued to split predictably 5-4 on almost all the hot-button issues, and Roberts himself has become more hard-edged and divisive, as his views on issues of race and executive power have clashed repeatedly with those of the court's liberal wing. This example shows that even with the best of intentions and personal skills, the ideological differences on the court make it difficult to bridge the divide.
