It needed 60 votes since the Democrats are filibustering all amendments they don’t like – it only got 45.
Poking around twitter and other sites, it appears one D did not vote and crossovers were as follows:
– The Maine Madams both voted with the Dems
– 7 Ds voted with the Republicans. (UPDATE) The Dems were Nelson, Conrad, Pryor, Casey, Dorgan, Bayh, and Kaufman. (Kaufman is the guy keeping the Biden seat warm.)
