Democrats came up short on MLK day promise. What's next for the push for a voting rights bill?

WASHINGTON – Democratic lawmakers will mark the Martin Luther King Jr. holiday having come up short on a promise to vote on a Senate rule change aimed at ushering through a voting rights bill.Senate Majority Leader Chuck Schumer announced Thursday the Senate will not take up House-passed voting rights legislation until Tuesday, breaking his deadline to vote on a rule change by the federal holiday honoring the late civil rights leader. Kyrsten Sinema, Joe Manchin defend filibuster, likely crushing Biden's hopes of passing voting rights billThe upcoming vote comes after President Joe Biden's unsuccessful effort on Capitol Hill to persuade Senate Democrats to pass a voting rights bill –  and a week in which he traveled to Atlanta and gave a speech pushing lawmakers to lift the legislative hurdle that has allowed Republicans to stall much of his agenda: the filibuster. Biden and most Democrats want to make an exception to the filibuster to allow a voting rights bill to pass with a majority vote, but without Manchin and Sinema, they don't have the support to change the rules. “Eliminating the 60-vote threshold will simply guarantee that we lose a critical tool that we need to safeguard our democracy from threats in the years to come,” said the Arizona Democrat.After Biden's meeting, Manchin once again stated he wouldn't agree to carving out a filibuster exception for voting rights, saying in a statement, "As I have said before, I will not vote to eliminate or weaken the filibuster."Biden met with Manchin and Sinema Thursday evening.
