They are opting instead to let voters in the remaining primaries have their say.

"There is not a rush for us to come in and intervene," said Rep. Mike Doyle, from the state's southwest corner. "The people of Pennsylvania got a chance to speak. I don't have a problem letting other folks have their say, either."

The state has 29 Democratic superdelegates. Fifteen have committed to Clinton and five to Sen. Barack Obama, and three remain to be selected by state party leaders.

Former elected officials and party leaders, the superdelegates from each state are free to vote for whomever they please at the late-August Democratic National Convention in Denver.

They are expected to decide the race for the presidential nomination, even after the coming primaries in Indiana and North Carolina.

Doyle's district spans 54 mostly blue-collar municipalities, including Pittsburgh. He said he might have sided with Obama had the candidate won his district by a wide margin. But the Illinois senator captured the district by only 4 percentage points.

Four other uncommitted superdelegates are members of the House: Bob Brady, Chris Carney, Tim Holden, and Jason Altmire.

"Certainly, what's happened in our district will be the single biggest factor in casting my vote as a super delegate," said Carney, who represents parts of 14 counties in central and northeastern Pennsylvania. With the exception of tiny Union County, all went for Clinton. "I want to do what's best for our country and what's best for our district, but the time for that decision is later."

Altmire, whose district spans six counties along the border with Ohio, said weighing in now would amount to a "rush to judgment."

"After the American people have spoken, I will decide which candidate will receive my vote as a superdelegate," he said. "The most important factor in my decision will be preserving the integrity of our national democratic process and ensuring that the will of the American people is followed."

Karen Warrington, Brady's spokeswoman, said the Philadelphia lawmaker "has indicated he will stick by his pledge to follow the lead of his constituents in deciding who to support for president, but he has not indicated when that announcement will be made."

Brady's district went overwhelmingly for Obama.

The sixth uncommitted superdelegate, Bill George, the longtime head of the Pennsylvania AFL-CIO, hasn't made up his mind, either. George plans to study Tuesday's results in closer detail before making up his mind, his spokesman Jim Deegan said.

Obama's superdelegates apparently remain firmly behind him.

Rep. Chaka Fattah, of Philadelphia, said none of Obama's superdelegates were wavering, himself included: "He won 80 percent of the votes in my district. What part of those results should make me waver?"

Adam Abrams, spokesman for Rep. Patrick Murphy, who represents Bucks County, said Murphy was not changing his mind.

Sen. Bob Casey said, "I was proud to support him. . . . He will do well in every region, and he will beat John McCain."

Carol Ann Campbell, a former city councilwoman, and Leon Lynch, a retired United Steelworkers of America union official, could not be reached for comment.

Three additional superdelegates will be chosen by Gov. Rendell and voted on by the State Democratic Party by June 7. Rendell, a superdelegate himself, is Clinton's biggest booster in the state.
