The Caucus, a blog by the New York Times, has an interesting post calling Sam Brownback the “Wilberforce Republican“

If you don’t know who he is, never fear—Hollywood is coming to the rescue with Friday’s release of “Amazing Grace.” The film details Mr. Wilberforce’s successful, 20-year effort as a British member of parliament to abolish the slave trade in the British Empire. He was inspired by his evangelical Christian beliefs. And Mr. Brownback, a devout Catholic who was previously an evangelical Protestant, “is deeply inspired by William Wilberforce,” said Brian Hart, his campaign spokesman.
A March 2006 article in The Economist first named Mr. Brownback a “Wilberforce Republican,” referring to his faith-grounded efforts to end human trafficking, fight genocide and AIDS in Africa and to reform prisons.
The Kansas senator is running with the association. Two weeks ago, he introduced a bill to honor the British abolitionist, and today, he will participate in a panel discussion following a screening of “Amazing Grace” in Los Angeles.

“We must continue to follow Wilberforce’s example and fight for the dignity and freedom of every person,” Mr. Brownback said in a press release about the bill. “It is intolerable that 200 years after Britain banned its slave trade, there are still hundreds of thousands of victims of human trafficking who are used as bonded labors, sex slaves, and in other horrifying capacities.”
