Deny the President his administration using a tactic that you yourself invoked in the process:

Ben Nelson To Filibuster Key Obama Labor Nominee – Yahoo! News

“Mr. Becker’s previous statements strongly indicate that he would take an aggressive personal agenda to the NLRB, and that he would pursue a personal agenda there, rather than that of the Administration,” said Senator Nelson. “This is of great concern, considering that the Board’s main responsibility is to resolve labor disputes with an even and impartial hand. In addition, the nominee’s statements fly in the face of Nebraska’s Right to Work laws, which have been credited in part with our excellent business climate that has attracted employers and many good jobs to Nebraska. Considering these matters, I will oppose the upcoming cloture motion and the nomination.”

Filibustering is kind of like jury nullification: there is a time and a place but you had better have a good excuse to use it. Otherwise you end up with tyranny of the minority. And I would not qualify a disagreement with a person’s private views a “good excuse,” to filibuster.

So this begs the question: if Sen. Nelson was so opposed to this man would he be opposed who had just as strong of opinions in the opposite direction? Somebody who had a history as a union busting advisor? While I would hope that he would based upon principle, I have a feeling that hope would be misplaced.
