Ron Brownstein in the Atlantic:

[T]here is a gnawing anxiety among voting-rights advocates that even if Democrats find a way to roll back the Senate filibuster and pass new federal legislation safeguarding access to the ballot, the Republican-appointed majority on the Supreme Court might still strike it down.

Last week’s Supreme Court ruling, in which the six Republican-appointed justices outvoted the three appointed by Democrats to uphold two Arizona laws that critics called racially discriminatory, has elevated that concern to a new height. It is forcing congressional Democrats and their allies to confront the question of whether it’s possible to “court-proof” their efforts to protect voting rights.
