"I would say that the George Bush Library's presence on campus may be misleading," said Tony Listi, a CampusReform.org regional director.

He said the evaluation of the SMU's political climate was based on several factors. Liberal SMU student groups outnumber conservative groups by five to one, and 84 percent of the school's faculty and staff who donated in the 2008 presidential election gave to Democratic candidates.

"We think that political contribution data indicates a political bias on the campus of Southern Methodist University," Listi said.

Listi also said that all incoming freshmen were required to read President Barack Obama's memoir, "Dreams From My Father."

"It seems like this is just a program of indoctrination," Listi said.

SMU declined to comment on the website's findings.
