And again, DU proves that it doesn't know how things work.
DHS could be funded tomorrow, minus 0's unconstitutional and judicially blocked power grab, if the Senate Dems would allow debate on the funding bill to move forward. McConnell needs to schedule a roll call vote every 30 minutes on taking up the House bill until 6 of the Dems break and cross the aisle. Even if all the Dems leave the chamber, they look bad for missing votes.
And I believe there is a method to compel attendance for absent Senators, so it's not like they can leave town and dodge out. It's a federal law they'd be dodging, they'd have to leave the country.
