Arlen Specter has died.

He was 82.

ADDED: He played an important role in Supreme Court nominations:

Arriving on Capitol Hill in 1981, he became a dominant force during the Judiciary Committee’s rancorous Supreme Court nomination battles. More than anyone else, he helped defeat conservative nominee Robert Bork in 1987, and his aggressive questioning of law professor Anita Hill four years later — he accused her of “flat-out perjury” — helped secure Clarence Thomas’s confirmation....

“He was a Rockefeller Republican, a liberal Republican, and was willing to take on Presidents Reagan and Bush, and became a true leader in the bipartisan efforts that strengthened all the civil rights laws and defeated Bork,” said Ralph G. Neas, a longtime civil rights and health-care advocate.

“Then you had a line of demarcation,” Neas said, beginning with Thomas’s Supreme Court nomination and continuing with the Republican majorities in the House and the Senate after the 1994 midterm elections. “Arlen Specter became an especially cautious politician,” Neas said....

After Sen. Specter warned President George W. Bush not to nominate judges who would overturn Roe v. Wade — the 1973 Supreme Court case that essentially legalized abortion rights — conservative Republicans protested his appointment to the Judiciary Committee. Sen. Specter later said he would not use a “litmus test” to deny confirmation to abortion opponents.

He presided over the confirmations of Supreme Court Justices John G. Roberts Jr. and Samuel A. Alito Jr. and was a key force behind passage of some of the Bush administration’s controversial anti-terrorism laws, including the Patriot Act. But as controversy erupted over the government’s handling of detainees at Guantanamo Bay, Cuba, Sen. Specter became a leading proponent of habeas corpus rights for unlawful combatants.

I was just watching old clips from the Bork and the Thomas nomination hearings — because, after the VP debate, I wanted to review Joe Biden's performance.
