HARRISBURG -- A state labor organization's "report card" on the voting records of Pennsylvania's congressional delegation ranks U.S. Sen. Rick Santorum at the bottom.

Bill George, president of the state AFL-CIO, released the report card yesterday.

Mr. Santorum, a two-term Republican who is facing a difficult re-election battle next year against presumed Democratic candidate Robert Casey Jr., emerged with the lowest score of the delegation on 14 issues, including raising the minimum wage; protecting Medicare and Medicaid for senior citizens and low-income people; preventing workers from working forced overtime; and losing American jobs to companies overseas.

"If one of my children brought home a report card like this, he'd be grounded for a year," said Diane Topakian, political director for the Service Employees International Union, which represents nursing home and health care workers.

Democratic congressmen, including U.S. Rep. Mike Doyle of Swissvale, scored well.

Republicans generally scored poorly, although U.S. Sen. Arlen Specter and U.S. Reps. Tim Murphy and Melissa Hart did a little better than Mr. Santorum.

Mr. George said the report card is part of a new campaign called "Who's on Our Side?" It is aimed at "holding the Pennsylvania congressional delegation accountable for the votes they cast for or against the priorities of working families."

A similar AFL-CIO survey will be conducted in 12 other states.

Santorum campaign spokeswoman Virginia Davis said she wasn't surprised that a "partisan political organization'' like the AFL-CIO "would look at only a handful of votes instead of looking at the senator's comprehensive record."

That record, she said, is "pro-family, pro-economy and pro-worker."

The AFL-CIO's negative assessment of Mr. Santorum is in contrast to praise he's gotten from a rival labor group, the Teamsters union, which recently commended him for his efforts to protect the "financial security of workers' pensions."

"We are grateful to him for everything he has done,'' said Pennsylvania Teamsters official Frank Gillen.

Mr. George said the 14 issues "for working families" that were included on the report card weren't intentionally stacked against Mr. Santorum.

Dan Schulder of the Alliance for Retired Americans said he disagreed with recent TV and print ads by Americans for Job Security, praising Mr. Santorum for his efforts on the Social Security issue.

"That's like thanking Mrs. O'Leary's cow for starting the fire that destroyed the Chicago skyline and provided a better view of the moon," he quipped.

The only one of the 14 issues that Mr. Santorum voted "correctly'' on, according to the AFL-CIO, was a bill to spend $286 billion to "modernize our nation's transportation infrastructure and create more than one million jobs."

He was assailed for "supporting a trade agreement that will send jobs overseas, opposing increasing the minimum wage to $7.25 an hour and sponsoring a bill to weaken wage and overtime protections for millions of workers."
