The Senate was set to consider more than 100 amendments late Wednesday and into Thursday morning as they hammer out a budget resolution that will launch Republicans’ Obamacare repeal effort, involving several votes on Democratic proposals that have almost no chance of being passed.

The amendment votes, which require 60 votes to pass, were seen largely as a delay tactic from Democrats before a final vote on the resolution, which could come in the early morning hours of Thursday. At the end of the grueling process, passage of the resolution will only need 51 votes, and it will set up GOP work on repealing the healthcare law.
