When will congressional Democrats realize that Joe Manchin is doing them a favor? In a column published Sunday in the Charleston Gazette-Mail, the West Virginia senator gave them two things they haven¡¯t had since Joe Biden became president: a message and a strategy.

Manchin has been clear from the start that he¡¯s inclined neither to get rid of the filibuster nor to support the For the People Act, the so-called voting-rights legislation that Democrats have already passed in the House. Last month, he expressed his preference for the John Lewis Voting Rights Advancement Act, which is more narrowly framed.

Manchin¡¯s column implicitly raises a crucial question: Why, if the For the People Act is so comprehensive in protecting voting rights, is the John Lewis Voting Rights Advancement Act even necessary?
