Two opposing political ideologies will square off tonight when Michael Moore and Michael Gallagher visit Penn State to campaign to potential voters with 11 days left until the presidential election.

Nationally syndicated radio talk-show host Gallagher will appear at 9 p.m. in 100 Thomas.

Moore, director of the award-winning Fahrenheit 9/11, will speak at 9:30 p.m. at the Bryce Jordan Center (BJC).

Gallagher will premiere a screening of the film FahrenHYPE 9/11, a film opposing Moore's documentary. No tickets are required and admission is free, but seating is limited to the first 700 people in attendance. DVDs of the film will be available after the screening.

Gallagher also will broadcast his regularly scheduled show at the Holiday Inn Express, 1925 Waddle Road, beginning at 9 a.m. today. He has also challenged Michael Moore to a debate at 5 p.m. at WKPS-FM (90.7), The Lion, Penn State's student radio station.

Andy Nagypal, host of Radio Free Penn State, said a debate between Moore and Gallagher did not seem promising.

"It doesn't look very likely," Nagypal said. "I contacted the College Democrats to get the word out but no one has contacted me directly about the debate. The invitation is still open."

Moore feels that encouraging people to vote is more important than a radio debate, said Terri Hardesty, Moore's spokeswoman.

"He is not interested in these people challenging him to these debates," Hardesty said. "He's on a mission to get people to vote and that's all he's worried about right now."

Moore's appearance is sponsored by the College Democrats and will be held at the Bryce Jordan Center. Though it is free, tickets are necessary for entry to the event.

Moore's speech will begin at 9:30 p.m. Doors will open at 8 p.m. and seating is on a first-come, first-serve basis. No signs or backpacks will be permitted inside the arena.

Bernie Punt, Jordan Center marketing manager, said tickets for the 90-minute event are going quickly.

"We expect to be sold out tonight," Punt said last night. "All 10,000 seats should be filled."

Penn State spokesman Bill Mahon said protests would be permitted outside the Jordan Center.

"We welcome free speech as long as they aren't interfering with others' right to listen to Moore's speech," he said. "That's appropriate on a college campus."

Mahon added that the Homecoming parade should not cause a problem for traffic on its way to see Moore.

"The parade should be past the BJC by the time the doors open for Moore's event, but police are still notified that traffic may cause a problem in that area."

Parking for the Gallagher event is free and will be at the Eisenhower Parking Deck.

Those who want to see Moore's speech can park at the Stadium West, which will only be accessible from Park Avenue, and the Jordan East lot, which can only be entered south of Curtin Road, from University Drive or Porter Road.

Gallagher's appearance is sponsored by the Young Americans for Freedom (YAF).

"They contacted me to partner together and bring the conservative message to PSU," YAF chairman Pete Roy said.
