The astounding show of Republican recklessness that led to last month's government shutdown made one thing very clear. The new Republican Party — the one ruled by the Tea Party — isn't interested in making our government work. They want to break it.

Now, as if shutting down the government of the United States, furloughing hundreds of thousands of government employees, wasting billions of dollars and threatening to wreck America's economy wasn't enough, Republicans in Congress have set their sights on a new target: our justice system.

Yesterday, Senate Republicans took their campaign against our government to a whole new level when they blocked the nomination of Nina Pillard to the U.S. Court of Appeals for the District of Columbia Circuit, which is widely considered to be the nation's second-highest court behind the Supreme Court.

Pillard is one of President Obama's three nominees to fill vacancies on the D.C. Circuit, which is currently operating with nearly one-third of its active judgeships vacant. All three nominees have extraordinary professional qualifications. All three have support from across the ideological spectrum. Yet Senate Republicans are vowing to filibuster all three simply because they were nominated by President Obama.

One of the most basic functions of the U.S. Senate is to provide "advice and consent" to the president on his nominations to executive agencies and to the federal courts. For most of our country's history, the Senate has generally taken this constitutional order responsibly, using its power to block only nominees whom senators found unqualified or dangerously far out of the mainstream. That is, until now.

The same party that shut down the government in an attempt to nullify a duly-enacted law that it does not like is now trying to prevent a twice-elected president from filling vacancies on an important court — a duty entrusted to him by the Constitution.

There's a reason Republican obstructionists have targeted the D.C. Circuit. The court has the last word on important federal laws and administrative rules on issues ranging from clean air regulations to workers' rights to cigarette labeling requirements to presidential recess appointments. Basically, just about any area that we regulate through our federal government is going to be affected by the D.C. Circuit. And it is currently dominated by conservative ideologues: nine of the 14 judges on the court (including "active" judges and senior judges who participate in panel decisions) were nominated by Republican presidents seeking to remake the courts in their ideological image.

Republicans want to keep it this way. President Obama has nominated five people to the court, yet Senate Republicans have allowed only one of these nominees to so much as receive a confirmation vote. By comparison, the Senate confirmed four of George W. Bush's nominees to the court and eight of Ronald Reagan's. In fact, the ninth, tenth, and eleventh seats that Republicans today demand remain vacant are ones that they ensured were filled when George W. Bush was president.

To give you an idea of just how conservative this court is as a result, just this month a George W. Bush nominee and a George H.W. Bush nominee ruled that employers who oppose birth control should be able to deny their employees access to affordable contraception through their insurance plans — an absurd twisting of the true meaning of religious liberty. A few months ago, the court ruled that a law requiring employers to display a poster listing employees' legal rights violates the free speech rights of the employers. No, really!

Unable to win national elections, Republicans are trying to hold on to what power they still have — and that includes control of the powerful D.C. Circuit. Just like they couldn't accept that the Affordable Care Act was the law of the land, the Tea Party won't admit that Americans chose President Obama to be the one making picks to the federal courts.

The Tea Party thinks that it has some sort of intellectual property claim on the U.S. Constitution. But sometimes I wonder if its leaders have even read it.
