What was strengthened by Wes berry v. Sanders?

The Supreme Court case Wesberry v. Sanders (1964) strengthened the principle of "one person, one vote" by ruling that congressional districts must have roughly equal populations. This decision aimed to ensure that each citizen's vote carries the same weight in the electoral process, thereby reinforcing the democratic principle of equal representation. The ruling mandated that states must redraw district lines to achieve population equality, addressing issues of disproportionate representation.
