WASHINGTON — House Democrats passed sweeping voting and ethics legislation Wednesday over unanimous Republican opposition, advancing to the Senate what would be the largest overhaul of the U.S. election law in at least a generation.

House Resolution 1, which touches on virtually every aspect of the electoral process, was approved on a near party-line 220-210 vote. It would restrict partisan gerrymandering of congressional districts, strike down hurdles to voting and bring transparency to a murky campaign finance system that allows wealthy donors to anonymously bankroll political causes.

The bill is a powerful counterweight to voting rights restrictions advancing in Republican-controlled statehouses across the country in the wake of Donald Trump’s repeated false claims of a stolen 2020 election. Yet it faces an uncertain fate in the Democratic-controlled Senate, where it has little chance of passing without changes to procedural rules that currently allow Republicans to block it.

The stakes in the outcome are monumental, cutting to the foundational idea that one person equals one vote, and carrying with it the potential to shape election outcomes for years to come. It also offers a test of how hard President Joe Biden and his party are willing to fight for their priorities, as well as those of their voters.

This bill “will put a stop at the voter suppression that we’re seeing debated right now,” said Rep. Nikema Williams, a new congresswoman who represents the Georgia district that deceased voting rights champion John Lewis held for years. “This bill is the ‘Good Trouble’ he fought for his entire life.”
