In his farewell speech, US Senator Arlen Specter of Pennsylvania called on Congress  to move quickly to counter the burgeoning right-wing extremism of the Roberts Court and the Republican caucus. Specter, who was first elected to the US Senate in 1980 as a Republican, spoke about how the Supreme Court under Chief Justice John Roberts has shown little respect for their own precedents or congressional fact-finding while pursuing a hard line pro-corporate bent . The increasingly conservative  Court has consistently ruled in favor of corporations  over the rights of workers and consumers, and the concerns of environmental protection and fair elections. Specter specifically pointed to the Roberts Court’s decision in Citizens United, which gave corporations the right to spend unlimited and undisclosed funds from their general treasuries in elections and overturned decades of Court precedents and congressional measures limiting corporate influence in politics. Specter said :
This Congress should try to stop the Supreme Court from further eroding the constitutional mandate of Separation of Powers. The Supreme Court has been eating Congress’s lunch by invalidating legislation with judicial activism after nominees commit under oath in confirmation proceedings to respect congressional fact finding and precedents, that is stare decisis.
The recent decision in Citizens United is illustrative: ignoring a massive congressional record and reversing recent decisions, Chief Justice Roberts and Justice Alito repudiated their confirmation testimony, given under oath, and provided the key votes to permit corporations and unions to secretly pay for political advertising, thus effectively undermining the basic democratic principle of the power of one person, one vote.
Chief Roberts promised to just “call balls and strikes,” and then he moved the bases.
Specter also blasted Republican obstructionism in the Senate. He said that even though 59 Senators backed ending debate on the DISCLOSE Act, which would have required groups to publicly disclose their donors, the important bill never received an up-or-down vote due to Republican procedural moves:
Repeatedly, senior Republican Senators have recently abandoned long held positions out of fear of losing their seats over a single vote or because of party discipline. With 59 votes for cloture on this side of the aisle, not a single Republican would provide the sixtieth vote for many important legislative initiatives, such as identifying campaign contributors to stop secret contributions.
The Pennsylvanian later criticized the GOP for preventing judicial nominees from also having up-or-down votes:
Important positions are left open for months, but the Senate agenda today is filled with un-acted upon judicial and executive nominees. And many of those judicial nominees are in areas where there is an emergency backlog.
When discussing how Senate Republican leaders, such as Jim DeMint  (R-SC), supported ultraconservative candidates  against Sens. Lisa Murkowski (R-AK) and Bob Bennett (R-UT), and Rep. Mike Castle (R-DE), Specter condemned the GOP’s embrace of “right-wing extremists,” adding : “Eating or defeating your own is a form of sophisticated cannibalism.”
