WASHINGTON – Refusing to be brushed off by Democratic opposition in the Senate, President Bush plans to nominate for a second time 20 people who did not receive up or down votes on their nominations for federal judgeships.

The Democrats’ ability to stall certain White House picks for the federal bench was one of the most contentious issues of Mr. Bush’s first term. During the past two years, despite the GOP majority in the Senate, Democrats used filibusters to prevent final votes from occurring on 10 of 34 of Mr. Bush’s nominees to federal appeals courts.

“The president nominated highly qualified individuals to the federal courts during his first term, but the Senate failed to vote on many nominations,” said a White House spokesman, Scott McClellan, in a statement issued yesterday. “Unfortunately, this only exacerbates the issue of judicial vacancies, compounds the backlog of cases, and delays timely justice for the American people.”

Dr. Bill Frist, the Senate majority leader, called for quick action and issued a statement that pressured Senator Specter, a Republican of Pennsylvania, to support the president’s nominees. Mr. Specter, a moderate Republican, recently won the backing of Senate Judiciary Committee Republicans to be their new chairman despite his statement that judges who oppose abortion would have a difficult time gaining Senate confirmation, given the opposition from Democrats.

“The president has decided to renominate many highly qualified and capable individuals to serve as federal judges,” Dr. Frist said. “I look forward to working with Senator Specter, other Judiciary Committee members, and my colleagues to ensure quick action and up and down votes on these judicial nominees.”

Democrats reacted with irritation.

“I was extremely disappointed to learn today that the president intends to begin the new Congress by resubmitting extremist judicial nominees,” the Senate minority leader, Harry Reid of Nevada, said in a statement.” Last Congress, Senate Democrats worked with the president to approve 204 judicial nominees, rejecting only 10 of the most extreme.”

Ralph Neas, head of People for the American Way, which worked to block several of Mr. Bush’s appointments to the courts, said Mr. Bush’s decision signaled his renewal of partisan warfare. “The president and his team want to pack the federal courts with right-wing ideologues and roll back decades of progress in social justice,” he said.

When the 109th Congress convenes on January 4, Mr. Bush intends to renominate the following 12 individuals for the U.S. Court of Appeals:

Terrence Boyle, 4th Circuit; Priscilla Richman Owen, 5th Circuit; David McKeague, 6th Circuit; Susan Bieke Neilson, 6th Circuit; Henry Saad, 6th Circuit; Richard Griffin, 6th Circuit; William Pryor, 11th Circuit; William Gerry Myers III, 9th Circuit; Janice Rogers Brown, District of Columbia Circuit; Brett Kavanaugh, District of Columbia Circuit; William James Haynes II, 4th Circuit, and Thomas Griffith, District of Columbia Circuit.

Mr. Bush also intends to nominate again the following eight people to U.S. District Court positions:

James Dever III, Eastern District, North Carolina; Thomas Ludington, Eastern District, Michigan; Robert Conrad, Western District, North Carolina; Daniel Ryan, Eastern District, Michigan; Peter Sheridan, New Jersey; Paul Crotty, Southern District, New York; Sean Cox, Eastern District, Michigan, and J. Michael Seabright, Hawaii.
