The Progressive Marxist democrat party, however, has plans to change Senate rules to disallow amendments.
I have read that "usually" it takes 67 votes to change a senate rule, but I'm not sure if that applies to reconciliation rules. e. g. to disallow amendments. Some say that the senate Dems don't really want to change the rules, because they don't want to lose their individual powers to become like members of the House.
Even if possible, using legislative tricks to pass a hugely unpopular bill would cause strife that would last for many years.
