Democratic insiders are assembling a coalition behind the scenes to wage an all-out war on the Senate filibuster in bullish anticipation of sweeping the 2020 election and passing an ambitious progressive agenda.

Veteran party operatives, activist groups and supportive senators are coordinating message and strategy to dial up the pressure to quickly end the 60-vote threshold early next year, fearing that preservation of the rule will enable Republicans to kill Joe Biden’s legislative agenda in its cradle.

They’re consolidating that effort under a new coalition called Fix Our Senate and run by Eli Zupnick, a former communications director for No. 3 Democratic Sen. Patty Murray, D-Wash…

“Our goal is to lift the filibuster higher on progressives’ agendas in advance of November and help them make it clear to a future President Biden and Senate leadership that they expect and demand speedy Senate rules reform in 2021 and will not accept more gridlock, delays, and excuses,” Zupnick said. “We are going to be very focused on the need for speedy action.”
