Senate Democrats brace for defeat on signature voting and election bill amid stiff GOP resistance

Senate Democrats are on track to suffer a stinging defeat Tuesday with Republican opposition expected to sink a voting and election bill that Democrats have made a signature priority, an outcome that will underscore the limits of the party's power with the narrowest possible Senate majority.

Democrats have set up a key test vote on the bill that they have pitched as a necessary counter to state-level efforts to restrict voting access, but Republicans have united against it, decrying it as a partisan power grab and a federal overreach into state voting and election systems. Democrats have also faced pushback over the legislation from a member of their own caucus: pivotal swing vote Sen. Joe Manchin of West Virginia.
