You should read the article. They do not need to ammend the filibuster. They are cheating by making an allowable minor editorial change to a bill that has already been slated for a vote (hence too late to filibuster), and the minor editorial change is to replace all the text with the text of the voting theft bill.
Because of our most stupid spineless bamboozled gutless representative at the hill letting the 2020 election steal slide now the evil demonic rats are emboldened and nothing is going to stop them. Sadly the rats will have their way...consider the Filibuster nuked! The rats are slimy cunning evil and know that they have the most powerful institutions in their corner...They have the freedom to destruct a nation and to do whatever they damn well please. I blame a lot of this on McConnell, Graham McCarthy and the rest of the POS RINOS. They should have fought alongside their base and drag the rats through the mud with hearings and court proceedings against the big election heist. But instead they ran to their nearest office corner and coward like little wimpering dogs!
