It was 214-216, not 215-215.
No, it was 215-215 but one of the Republican dissenters switched his vote so the matter could be easily rescheduled. Santos would have made a difference: I sadly predict this seat goes Democrat on Feb. 13.
You were not paying attention. If Santos had voted that would raise it to 215 to 216, but at that point Blake Moore, R-Utah would have voted for the resolution making it 216 to 215. He switched his vote because that gives him the right to move for reconsideration of the bill.
