Matthew Dowd, former chief strategist for President George W. Bush, on Sunday described a bill in Arizona as using religion to discriminate against gays.

The measure, which states that individuals and businesses can refuse service based on their religious beliefs, cleared the Senate on Wednesday and the House the following day. Calling the measure “controversial,” Republican Governor Jan Brewer said she will decide whether to sign the bill next week.

Opponents of the measure say it would allow individuals and businesses to discriminate against gays.

ABC News This Week host Martha Raddatz asked Dowd to predict whether Brewer would sign the bill into law.

“I think, in the end, Governor Brewer is probably going to veto this because it seems like an easy veto for her to do because of everything that's going on in the business economy there,” Dowd answered.

“This is one of those problems when people use religion as a way to sort of enforce discriminatory practices. People used religion back in the 1860s when they defended slavery. They used religion to defend slavery,” he emphasized.

We've used religion to go to war. People have criticized Islam because they use religion to fight people and kill people.” Dowd added. (The video is embedded on this page. Visit our video library for more videos.)
