Manchin instead has called for a narrower measure -- the John Lewis Voting Rights Act -- aimed at restoring a key provision of the landmark 1965 law that was struck down by the Supreme Court eight years ago. But even that proposal, which would empower the federal government to challenge states that make changes to their election laws, stands little chance of winning over 10 Republicans -- and that has made Democrats even more perplexed at Manchin's strategy. "My question is: Are there 10 Republican votes for the John Lewis Voting Rights Act? Why are we talking about this if it also is going to fall short of the 60-vote threshold? So this is an abstraction," said Sen. Brian Schatz, a Hawaii Democrat. "My view is that anybody who holds the filibuster up as some key element of maintaining democracy has an obligation to be part of the group that produces 10 votes for something meaningful."... "Protecting the vote in America is not partisan," said Sen. Elizabeth Warren, a Massachusetts Democrat. "It's the responsibility of the United States Congress." "I mean that's an interesting thing to say in light of the fact that we are seeing all of these decidedly partisan bills coming out of state legislatures," said Sen. Raphael Warnock, a Georgia Democrat up for reelection next year, who spoke with Manchin Sunday night about the issue. "Somebody should tell the Republicans that."
