The bill that would give the workers 7 sick days only got 52 votes in the senate. Needs 60 to overcome the filibuster
Fact is they hid behind the parliamentarian, insisted on bipartisan legislation as a priority and then proceeded to cede the power granted to make that excuse a reality today.
Personally, I reject it all and know damn well this could all play out differently and it doesn't because ordinary people are just not a priority.
As you say, they have their reasons for keeping it.
Your claim would be more useful if you pointed out the vote was 52-43; with no great effort six Republicans voted for it, five Democrats are AWOL and Manchin for some reason I can't imagine voted against it.
The Senate also voted 26-69 against 60 more days of negotiations.
