(CNN)Senate Republicans blocked the John Lewis Voting Rights Act from advancing on Wednesday when the Senate took a procedural vote on whether to open debate on the legislation.

The final tally was 50 to 49 with GOP Sen. Lisa Murkowski of Alaska voting with Democrats in favor.

The John Lewis voting bill that the Senate considered is aimed at fighting voter suppression and restoring and updating key parts of the landmark Voting Rights Act, originally passed in 1965. The measure is named in honor of the civil rights icon and late Rep. John Lewis of Georgia.

At least 10 Republicans would have needed to join with all 50 members of the Senate Democratic caucus for the legislation to advance. That was not expected to happen as most Republicans have decried any Democratic attempts to enact new voting legislation in the current Congress as partisan and unnecessary.
