Friday was the deadline for independent and third-party candidates to file petitions to win a place on the Pennsylvania general election ballot.
Independent Ralph Nader and the Libertarian Partys Bob Barr will join McCain and Obama on the presidential ballot, unless their petitions are successfully challenged.
In the 8th Congressional District, two candidates independent Tom Lingenfelter and the Constitution Partys Jay Russell will join Democratic Rep. Patrick Murphy and Republican Tom Manion on the ballot.
In the 13th Congressional District, the Constitution Partys John McDermott will take on Democratic Rep. Allyson Schwartz and Republican Marina Kats.
The Libertarian Party will have the following candidates for statewide row offices: Gregory Teufel (attorney general), Betsy Summers (auditor general) and Berlie Etzel (treasurer).
McDermott is applauding a recent unanimous Pennsylvania Supreme Court decision that declared unconstitutional an amendment adding sexual orientation to the states Ethnic Intimidation Act. McDermott criticized Schwartz for voting for the amendment in 2001 when she was a member of the state Senate. Schwartz had no comment.
The court ruled that the legislature erred in inserting the language into an unrelated bill about agricultural crops.
A group called Repent America sued after members were arrested in Philadelphia in 2004 for preaching, during a festival for gays, that homosexuality is a sin.
McDermott argues that such hate-crime laws are designed to intimidate evangelical Christians, traditionalist Catholics and others opposed to the gay lifestyle. He blames the Democratic Party for pushing the issue.
"I will be more than happy to hang an Out of business; morally bankrupt sign on that partys national headquarters," he said.
Matt Taubenberger, the Republican candidate in the 170th Legislative District, plans to make the hiring of 1,300 new police officers one of his top priorities if elected.
Taubenberger supports the Commonwealth Officers Act, sponsored by state Rep. John Perzel. The state and municipalities would share the funding of 10,000 police officers across the state.
Taubenberger estimates that 400 of those officers would be assigned to districts in the Northeast and 576 in Montgomery County. The 170th district includes a portion of eastern Montgomery County.
"As a former probation officer, I know the importance of working with local law enforcement to fight crime and keep our neighborhoods safe," he said. "That is why I will work hand and hand with Rep. Perzel and other concerned elected officials to make public safety a top priority."
In addition, Taubenberger supports mandatory, concurrent five-year prison sentences for any repeat offender who commits a crime with a gun. He also supports the elimination of parole for any violent offender. And, he backs a proposal to require a majority vote of the parole board before an inmate is released.
Taubenberger faces Democrat Brendan Boyle for the seat of retiring Republican Rep. George Kenney. Taubenberger serves as director of constituent services for Kenney.
Meanwhile, Boyle has won the endorsement of the AFL-CIO.
"Brendan understands the labor movement and he understands that the decisions made in the state legislature directly affect working families in Philadelphia," said Pat Eiding, president of the local AFL-CIO. "Hell make a great addition to our Philadelphia delegation in Harrisburg."
The AFL-CIO, like some of the other unions that have endorsed Boyle, previously backed Kenney. Boyle lost bids to unseat Kenney in 2004 and 06.
