The only way dems can block, is with the filibuster in the Senate. Turtle needs to bring back a real filibuster. If the dems want to shut it down...make 'Em talk.
See how that goes over on C-Span when services are cut for Americans.
The secondary way is reconciliation. Pass in the House, the Senate caves and gives every illegal a Citizenship so dems bring it to the flow..I.E. no filibuster.. Then kill it in reconciliation, simple majority in both houses then.
