ROLL CALL: Senate GOP Wrestles With Whether to Undo the Nuclear Option.

Senate Democrats got rid of the filibuster last year for all nominations except Supreme Court nominees by reducing the threshold for breaking a filibuster to a simple majority. They did it using the nuclear option, which allowed them to essentially change Senate rules on a simple majority vote by overturning the ruling of the chair.

Republicans were livid because changes to Senate rules typically require a two-thirds majority.

But now that the genie is out of the bottle, some Republicans believe they should keep the nomination process as is.

Sen. Orrin G. Hatch, R-Utah, had been leading the charge in favor of leaving the issue alone, recently penning a couple of op-eds on the issue.

Sen. Ted Cruz, R-Texas, said he agreed with Hatch, noting that he believes it was a mistake for Democrats to trigger the nuclear option.

If they don’t feel some pain, they’ll never learn.
