In the name of preserving carefully negotiated legislation, Senate Democrats’ leaders united their caucus to vote down amendments that would have added the party’s Medicare expansion plan and expanded child tax credit into the final spending bill now moving through Congress.

That unity, though, was not universally enforced: soon after those votes, seven Democratic senators joined with Republicans to cast a pivotal vote shielding their private equity donors from a new corporate minimum tax.

The seven Democrats who joined the GOP to give private equity firms that $35 billion gift were: Senators Kyrsten Sinema and Mark Kelly of Arizona, Raphael Warnock and Jon Ossoff of Georgia, Jacky Rosen and Catherine Cortez Masto of Nevada, and Maggie Hassan of New Hampshire.
