And if the nuke option failed?
BINGO! And I don't think the votes were there this time to pass the "nuclear option" (I don't like that term). However, IF the Democrats break their word (good probability) in the future, then the "nuclear option" will definitely pass.
IF IT FAILED THE PEOPLE THAT VOTED AGAINST WOULD LOSE! Most of these people come from conservative states and this vote would finish them at their re-elections. Good grief! Why do you think the cowards signed the deal? they didn't want to VOTE!
